results for this questionWhat is a motor overload heater?What is a motor overload heater?Overload relays protect a motor by sensing the current going to the motor.Many of these use small heaters,often bi-metallic elements that bend when warmed by current to the motor.When current is too high for too long,heaters open the relay contacts carrying current to the coil of the contactor.The Basics Of Selecting Overload Relays results for this questionWhat is an overload relay?What is an overload relay?overload relay.A relay that opens a circuit when the load in the circuit exceeds a preset value,in order to provide overload protection; usually responds to excessive current,but may respond to excessive values of power,temperature,or other quantities.Overload Article about Overload by The Free DictionaryAllen Bradley Heater Overload Chart - Best Picture Of
