Description

■Remote-controlled motorized operating mechanism

3RV1 circuit-breakers are man-ually operated switching devices. They automatically trip in case of an overload or short circuit. Intentional, remote-con-trolled tripping is possible by means of a shunt release or an undervoltage release. Reclos-ing is only possible directly at the circuit-breaker.

The remote-controlled motorized operating mechanism allows the circuit-breakers to be opened and closed by electrical com-mands. This enables a load or an installation to be isolated from the power system or recon-nected to it from an operator panel.

The remote-controlled motorized operating mechanism is avail-able for circuit-breakers of• sizes S2 (In max. = 50 A) and• size S3 (In max. = 100 A)that are designed for control voltages of AC 230 V or DC 24 V. The circuit-breaker is fitted into the remote-controlled motor-ized operating mechanism as shown in the block diagram.

The circuit-breaker in the remote-controlled motorized operating mechanism can still be switched locally in the "MAN-UAL" position. In the "AUTO-MATIC" position, the circuit-breaker is switched by means of electrical commands. The switching commands must be at least 100 ms long. The remote-controlled motorized operating mechanism closes the circuit-breaker after 1 second at the lat-est. In the event of a power fail-ure during the switching operation, the circuit-breaker is guaranteed to remain in the ON or OFF position.

■Mounting accessories

Door-coupling rotary operating mechanisms

Circuit-breakers with a rotary operating mechanism can be mounted in a cubicle and oper-ated externally by means of a door-coupling rotary operating mechanism. When the cubicle door is closed, the operating mechanism is coupled. The coupling locks when the cir-cuit-breaker is closed. Inad-vertent opening of the door is prevented. This lock can be defeated by the maintenance staff. In the OFF position, the rotary operating mechanism can be prevented from reclos-ing by means of up to three padlocks. Once again, inad-vertent opening of the door is impossible.

Enclosures

Moulded-plastic enclosures with various dimensions for wall or flush mounting are available for installing individual circuit-breakers of sizes • S00 (In max. = 12 A)• S0 (In max. = 25 A)• S2 (In max. = 50 A)

The enclosures for wall mount-ing are designed for degree of protection IP 55, and the enclo-sures for flush mounting also fulfil degree of protection IP 55 on the front (the flush-mounted section complies with IP 20).

All enclosures are equipped with N and PE terminals. Two knockout cable entries for cable glands are provided at both the top and bottom, and further suitable entries are also pre-moulded on the rear. There is a knockout for indicator lights, which are available as accesso-ries, on top of the enclosure.

A circuit-breaker without acces-sories, equipped with one trans-verse and one lateral auxiliary contact, can be fitted into the narrow enclosures. In the wide enclosures and in the enclosure for S2 circuit-breakers there is also sufficient space for a later-ally mounted auxiliary release. Circuit-breakers with a signal-ling switch cannot be installed in the enclosures.

S00 circuit-breaker in enclosure with EMERGENCY STOP mushroom button

S2 circuit-breaker with attached isolator module and padlock

With S00 circuit-breakers, the switch rocker is operated via the actuator diaphragm of the enclosure. A locking device, capable of holding up to three padlocks, can be fitted onto the actuator diaphragm. These padlocks prevent the circuit-breaker from closing during maintenance work, for example.

A mushroom-shaped EMER-GENCY STOP handle can be fit-ted in place of the locking device. If it is actuated abruptly, the circuit-breaker opens and the mushroom-shaped handle latches. The handle can be unlatched again either by turn-ing it or by using a special key.

The circuit-breaker can then be reclosed.

The moulded-plastic enclosures of S0 and S2 circuit-breakers with a rotary operating mecha-nism are also fitted with a rotary operating mechanism.

The enclosures are available with black rotary operating mechanisms or with EMER-GENCY STOP rotary operating mechanisms with a red/yellow handle.

All rotary operating mecha-nisms can be locked in the OFF position with up to three pad-locks.

Front plates

Circuit-breakers are frequently required to be actuated in any enclosure. Front plates that include an actuator diaphragm for size S00 circuit-breakers or a rotary operating mechanism for size S0 to S3 circuit-break-ers are available for this pur-pose.

The front plates for size S00 are are equipped with a retaining frame, into which the circuit-breakers can be snapped.

For the front plates for sizes S0 to S3, a retaining frame for size S0 circuit-breakers is available.

■Mountable accessories

Busbar adapters

The circuit-breakers are mounted directly with the aid of busbar adapters on busbar sys-tems with 40 mm and 60 mm centre-line spacing, in order to save space and to permit infeed times and costs to be cut.

Busbar adapters for busbar systems with 40 mm centre-line spacing are suitable for copper busbars with a width of 12 to15 mm, while those with 60 mm centre-line spacing are suit-able for widths of 12 to 30 mm. The busbars can be 4 to 5 mm or 10 mm thick.

The circuit-breakers are snapped onto the adapter and connected on the line side. This prepared unit is then plugged directly onto the busbar system, and is thus connected both mechanically and electrically at the same time.

Refer to page 2/10 for busbar adapters for individual circuit-breakers and accessories.

Other busbar adapters for snap-mounting direct-on-line starters and reversing starters, as well as additional accesso-ries such as line terminals and outgoing terminals, busbar cop-per, etc., can be found in Part 13.

Insulated 3-phase-busbar systems

3-phase busbar systems pro-vide a simple, time-saving and straightforward means of feed-ing a series of adjacent 3RV1 S00, S0 and S2 circuit-breakers which are snap-mounted on a standard mounting rail.

The busbars are suitable for between 2 and 5 circuit-break-ers. Any kind of extension is possible however by clamping the tags of an additional busbar (rotated 180°) underneath the terminals of the last circuit-breaker.

Different sized circuit-breakers cannot be clamped together due to the different fixing dimensions. Special connectors are available for connecting 3-phase busbars for S0 circuit-breakers to busbars for S00 cir-cuit-breakers.

Busbars with larger modular spacings can be used for cir-cuit-breakers with laterally mounted accessories.

The circuit-breakers are sup-plied via appropriate line-side terminals.

3-phase busbar systems are safe against finger touch. They are designed for short circuits of the kind that can occur on the load side of the connected cir-cuit-breakers.

Solder pin connections

Solder pin connections are available for the main contacts and for the transverse auxiliary switch of S00 circuit-breakers.

The prepared connecting parts are clamped into the upper and lower screw terminals of the cir-cuit-breakers, allowing the latter to be soldered to a printed-cir-cuit board.

Plug-in socket

A plug-in socket is available for S3 circuit-breakers (In max. = 100 A). In addition to the plug-in socket, the installation kit also contains 6 plug-in contacts, which are necessary to convert the fixed-mounted circuit-breaker to a plug-in circuit-breaker. A specially adapted circuit-breaker should be used in conjunction with the plug-in socket (see page 2/10).

Due to the risk of arcing, a closed circuit-breaker must never be pulled out of the plug-in socket or plugged into it. A tripping pin on the circuit-breaker is therefore activated if an attempt is made to do so. This tripping pin only allows the circuit-breaker to be closed when it is plugged in and trips the breaker if an attempt is made to remove it.

Rear connection

Circuit-breakers are usually connected on the front. It is often preferable to connect the circuit-breaker on the rear how-ever, for example in the case of large circuit-breakers and con-ductor cross-sections or if a busbar is connected. A "rear main conductor connection" kit be supplied for S3 circuit-break-ers, to enable this alternative to be offered for SIRIUS 3R circuit-breakers as well.
