Overload Relay

An overload relay can be defined as an electrical device mainly designed for imitating the heating prototypes of the electric motor, as well as breakups the flow of current when the heat detecting device in the relay attains a fixed temperature. The designing of an overload relay can be done with a heater coupled with generally closed connections that unlock when once the heater acquires too hot. The connections of an overload relay can be connected in series as well as placed among the motor & contactor itself to avoid the motor from restarting when the overload trips.
