What is the function of thermal relay?

What Is the Function of Thermal Overload Relay? A thermal overload- relay is a relay designed to protect electrical systems from overheated conditions. It does not shut off power to the circuit but instead senses when the current has reached a high enough level and opens, allowing the motor to continue to run.

What are 2 types of overload relays?

Overload relays are typically one of two types: thermal relays or electrical relays. The overload mechanism inside thermal relays consists of a bimetallic strip in conjunction with a heating element.

What is meant by thermal relay?

A relay that opens or closes contacts with a bending mechanism as a result of the difference in the expansion coefficients of a bimetal, which is heated by the current. The thermal relay switches a magnetic contactor to protect a motor from overload.

What are the three types of overload relay?

A few different types of overload relays include Bimetal Overloads, Ambient-Compensated Overload Relay, and Electronic Overload Relays.
