II. Basic knowledge of contactor

III. Basic knowledge of thermal overload relay

IV. Basic knowledge of motor circuit breaker

Introduction to motor control and protection products

Contactor Basic concept: for remote connection and disjunction of circuit, frequent starting and control of motor and

other loads

Main applications: mainly used for controlling motors, and also used for controlling factory equipment,

electric heater, lights, various power units and other electrical loads

Thermal overload relay

Basic concept: provides multiple protections against overload, phase loss and interphase imbalance for

circuits and motors

Main applications: motor protection, and combination into motor starter with appropriate AC contactor

Contactor relay

Basic concept: also known as intermediate relay, used to transmit intermediate signals in the control circuit

Main applications: controls another channel or more channels of signals through one channel of control

signal; provides start, stop and linkage control; mainly used for controlling contractors

Motor circuit breaker

Basic concept: functionally replaces the combination of moulded case circuit breaker and thermal overload

relay

Main applications: provides isolation, short circuit, thermal overload and phase loss protections for small-

capacitor motors and circuits, and also used for switching the circuits that do not work frequently or for directly

starting the motor

Common problem analysis

Differences at coil supply frequency 50Hz or 60Hz

Problem in the contactor with 50Hz coil under 60Hz power supply:

Coil heating after long operating time, resulting in coil burnout

Problem in the contactor with 60Hz coil under 50Hz power supply:

Insufficient electromagnetic attraction, resulting in unreliable actuation

Differences between use classes AC-3 and AC-4

AC-4 is running under heavy load and AC-3 has relatively light load. In AC contactor

selection generally, the current selected under AC-4 is greater than that under AC-3, i.e.

running with less load.

For example: use HJX2-12 under AC-3 and use HJX2-25 under AC-4

AC-4 is generally used in severe service environment such as high operation frequency,

inching and positive and negative rotation.

For example: cement plant, tower crane and mine

heating

Working principle of thermal overload relay

Principle: The thermoelement is connected in the main circuit and its current flows through the motor. In case of

motor overload, the bimetallic strip is heated to the operating temperature, so that the thermal relay acts, the

contactor control circuit is disconnected, the contactor coil is powered off and released and the main circuit is

disconnected.

Motor circuit breaker application methods

Exclusive use

Circuit, motor and transformer protection

(Generally, small current specifications are mainly used for circuit and motor protection and

large current specifications for transformer protection)

Starter combination The starter combination is composed of the contactor or soft starter and the overload relay and

used for operation control and provides overload protection and short circuit protection for the

motor.

Motor circuit breaker application fields

Market overview

With small current specification, the motor circuit breaker is mainly used for starting and

protection of medium and small power motors.
