4/24 · Overload protection relays have adjustable current setting ranges to control their activation threshold. In addition to preventing electrical overload, they can also detect and protect against phase failures. Since these relays often operate in hot environments, they provide ambient temperature tolerances up to 60° C.

Thermal overload relays are conversely designed to measure a motor's heating profile; therefore, overload must occur for an extended period before the circuit is interrupted. Temperature control relays directly sense a motor's temperature using a thermistor or resistance thermal device (RTD) probe which is embedded in the motor winding
