Contactor & Control Relay Overloads

Contactor and control overload relays protect machinery from overheating, this includes the machine itself and the bearings, gears and coolants as the relay receives the corresponding signal and trips.


What is a Contactor and Control Overload Relay?


Often referred to as an overload relay, our generous range of contactor and control relay overloads offer users motor control within a multitude of environments.


It is important for users to have sufficient motor protection; electrical motors can be operated safely with the assistance of overload relays. They are predominantly designed for imitating the heating prototypes.


Within our range of contactor and control relay overloads, we feature thermal overload relays. A thermal overload relay is a protective device which cuts the power whenever the motor uses too much current for a long period of time.


These devices are directly related to circuit breakers, in design and in application. The difference being that a circuit breaker will disturb the circuit if an overload occurs for just a second, whereas a thermal overload will cut the power after a prolonged period of time.


Applications of a Contactor and Control Overload Relay


  • The majority of the time is to protect a motor

  • To detect both overload conditions and fault conditions to then announce trip command for a protective device

  • To deactivate a device whenever it pulls high current

  • Sometimes developed into microprocessor systems and solid-state electronics
