Over current release protection feature and functions, please refer to Fig. 1, earthed fault protection feature

and functions, please refer to Fig. 2.

M type intelligence over current controller protection feature and functions

Ammeter function: demonstrate each phase working current and earthed leaking current, show the

maximum phase current normally and the current or time when it's setting up, testing and making an

error.

Voltmeter function: indicate kinds of voltage of each wire and show the maximum normally.

Remote control and self-diagnostics function:

The controller has its own error self-diagnostics function: it would send error signal by “E” to indicate or

alarm when PC is making an error. And you could disconnect the circuit if you need when you restart

your computer.

When partial environment temperature partial runs up to 80℃, it could send alarm signal and disconnect

the circuit when lesser currents via. (For special orders)

Intelligent controller has overload, earthed, short circuit, load monitor, predicted alarm, release indication

(OCR) and etc. and all of the signals could be output through electrical contact or optical coupling which

would be convenient for user to connect external remote control unit. The electrical contact's capacity is

DC28V, 1A, AC125V, 1A.

Setting up function:

Use “set”, “+”, “_” and “save” these 4 buttons to set up all the parameters of the controller. Press “set up”

to the status you want to set (the status light would be on), and then press “+” or “_” button to adjust the

parameter to required value, then press “save” button. When “save” button light is on, the setting has

been locked up. The protection parameters of the controller couldn't be set up crosswise. When the

controller is back to reset after power cuts, press “set” button again and then check the setting

parameters circularly.

Testing function:

Use “set”, “+”, “_”, “release” and “unreleased” these buttons to check kinds of protection function and

feature of the controller and use “set”, “+”and “_” buttons to adjust a simulated failure test current.(Note:

don't press “save” to lock) and then use “release” or ” unreleased” buttons to test, the controller would go

ahead recovery processing. Press “release” button, the circuit would break. Press “unreleased” button,

the circuit wouldn't break and all the indication status are normal. If you want to do other test, please

press “return” or “clean” button after the test.

Note: for testing convenience, whether the earth leakage is setting in releasing or alarming position, the

test regards them as releasing treatment and the PRI is less than overload protection. In case there's

some error occurs during the testing, the controller would cut off the entire test automatically and then do

the recovery processing.

Load monitoring function:

Set two settings, ILC1 setting range (0.2-1) in and ILC2 setting range (0.2-1) In. the delay characteristic

of ILC1 is inverse characteristic, it's time setting is 1/2 of long delay setting; the delay characteristic of

ILC2 has two characteristics: one is inverse delay characteristic, it's time setting is 1/4 of long delay

setting. And the other is constant time lag; its delay time is 60S. The other delay function: the former is

used for disjunction junior unimportant load when the current is close to overload setting. And the latter is

used for making delay disjunction junior unimportant load when the current is beyond ILC1 setting, the

current would be decreased and keep the main circuit and important load circuit in power supply. When

the current is decreased into ILC2 and then gives the order to reconnect the circuits that have been cut

off after a certain delay, then recover the power supply of the entire system. There are two patterns of the

load monitoring from which users could choose one at random. About the monitoring characteristic,

please refer to fig.3 and 4, MCR release and imitate release protection. According to the special needs, it

could be shut off when doing the short delay releasing test.

MCR connecting and disjunction protection is mainly used for the switch off when the circuit is in error

status (the moment as the controller is turn on the power), the controller has the function to release the

circuit in low power short circuit current. The factory setting is 10KAm and the error is ±20%.(The other

setting could be done for the special needs.)

The controller has the function to send the releasing signal directly without the core's slice handling

when it is in super short circuit current.

Heat memory function

The controller has the mock duplex metal characteristics' memory function before the controller is

powered down when overloading and short circuit delay releasing. And the load energy would release

and finish short circuit in 30 minutes. The releasing time would be shorten, the controller would be power

down and the energy would be zero clearing when there's overloading and short delay during the

process.

If one of them doesn't work, you could take the entire old down and then take the new one on.The draw-out circuit breaker is made up of insert circuit breaker and draw base. The guiding rail inside the draw base could be pushed in and pull out, the insert circuit breaker is on the guiding rail of the in and out draw. It links and connects the major loop through the insert generatrix and bridge type contact on the draw base.There are three operation positions for draw-out circuit breakers: “Connecting”, “testing” and “breaking” positions. The position change could be realized by handle's procession and out of procession and the three positions' indication could be realized by the handle display on the draw-out base' beam.The major loop and the secondary circuit could be connected when it's in “connecting” position. The major loop would be disconnected and be separated by insulating barrier; only the secondary circuit is connected and could run necessary action test. Both the major loop and the secondary circuit would be disconnected when it's in “breaking” position. The draw-out circuit breaker has mechanical interlocking. The circuit breaker could be closed when it's in “connecting” or “testing” position and it couldn't be closed during the middle position between connecting and testing.

Installation, operation and maintenance

Installation

Please check if the specification of the circuit breaker is up to the mustard before installation.

Please check the insulating resistance of the circuit breaker by 500V mega meter before installation and

it should no less than 10MΩ when the ambient medium temperature is 20℃ ± 5℃ and the relevant

humidity level is 50%-70%, otherwise it should be parched to use until the insulating resistance meets

the demands.

The base should be in horizontal position and be fixed by Blot M10 when installation.

Please do the reliable earthed protection when installation and make the clear earthed mark in the

earthed place.

Please don't change the technical data of the upper or nether inlet line of the circuit.

When the installation is finished and connected with the wire according to the relevant connecting

diagram, please do the operation test below before the main power is turned on (the indication on the

draw-out circuit breaker's base is in “testing” position):

Check under voltage, shunt release, closing electromagnetic and voltage of the electrical operation

mechanism is match case or not. (The under voltage release must be turn power on before the circuit

breaker is closed.)

Move the handle on the veil up and down for seven times and then the “stored energy” is showed on the

panel with a click. When the energy storing is finished, press “1” button or make the closing

electromagnetic in power, and the circuit breaker would be closed reliably (in the case that the “return”

button could reset), moving the handle could store the energy again.

The electric is operated with power the “stored energy” is showed on the panel with a click. When the

energy storing is finished, the electric motor would cut power off automatically and then press “1” button

or make the closing electromagnetic in power, and the circuit breaker would be closed reliably.

Pressing under voltage, shunt release or “O” button on the veil, the release testing of the intelligent

release could make the circuit breaker cut when the circuit breaker is closed.

The plate of M and H type intelligent release as Fig. 21.22

The instruction of L type intelligent release as Table. 9

The buttons and signal lamps of H and M type intelligent release as Table.10

The controller can adjust settings on line, but this time the load current should be less than the current

setting.

generally it should be “In” ;. Press “+” and “-” button, the sliding scale is ≤2A once until it's close to

needed current. On top of that, press “save” button and then the storage indication light is on once and

off which means the long delay current setting value is finished saving.

--The setting of overload long delay time setting (tL): press “set” button again and the long delay time

status indication green light would be on and show the long delay time factory setting value (15s). Press

“+” for once, the time would be double added. If the time is too long, press “-” button. The time would be

double reduced for once. On top of that, press “save” button and then the storage indication light is off

which means the long delay time setting is finished saving.

The protect action and action time setting method of load monitoring, short delay, instantaneous, earthed

corresponding indicator light "Ir2" yellow light, and its action time setting time corresponds to the state of

its actions "tS" yellow light, and so on

The earthed time setting is in “off” position which means the fault status and earthed one is only alarming

but no release. The instantaneous setting is in “off” position which means the protection is been

cancelled. The controller has the function of self lock key and then goes into error handling status in

case there are error signals during the setting process.

Intelligent release set in the whole process, once the line broke down, setting function will be blocked

automatically entered to deal with line fault, and has been stored by setting the value of the

implementation of the protection.

Earthing and earth leakage protection

Single-phase earth fault current protection means more than a few hundred amperes of grounded metal protection, are generally used for neutral

grounding system directly. Controller are two different ways to protect

One is the internal transformer vector methods (ground protection), the controller based on three-phase current and neutral current vector and the

level to protect, according to the number of circuit breakers into a very 3PT, 4PT, (3P + N) T the three forms (diagram below). The ways are generally

applicable to balance the load; unbalanced motor load or load, generally speaking, only the police do not release

4PT Mode (3P+N) Mode3PT Mode

The other type is External leakage transformer means (residual current protection), plus direct access to the controller of a current transformer signal

output current protection, the general transformer secondary output current of 5A/1A (a current transformer when less than or equal to 400A) and

second for the 1A; 400A more than the second for the 5A, a higher sensitivity of the program, especially for dozens of amps from the beginning of the

smaller ground current protection

Earthing and earth leakage protection

Single-phase earth fault current protection means more than a few hundred amperes of grounded metal protection, are generally used for neutral

grounding system directly. Controller are two different ways to protect

One is the internal transformer vector methods (ground protection), the controller based on three-phase current and neutral current vector and the

level to protect, according to the number of circuit breakers into a very 3PT, 4PT, (3P + N) T the three forms (diagram below). The ways are generally

applicable to balance the load; unbalanced motor load or load, generally speaking, only the police do not release

4PT Mode (3P+N) Mode3PT Mode

The other type is External leakage transformer means (residual current protection), plus direct access to the controller of a current transformer signal

output current protection, the general transformer secondary output current of 5A/1A (a current transformer when less than or equal to 400A) and

second for the 1A; 400A more than the second for the 5A, a higher sensitivity of the program, especially for dozens of amps from the beginning of the

smaller ground current protection
