Thermal overload relay sqare d 1.8-2.3 td1.8 class 9065

Thermal relays are electromechanical protective devices used to protect electric motors from overloads and rotor locks. Thermal relays consist of a bimetallic strip that bends when the current flowing through it exceeds a preset value. When the bimetal strip bends, it cuts power to the motor, protecting it from damage.

Manual reset-ready thermal relays feature a reset button that allows the user to reset the relay manually, without the need to replace the fuse. This type of thermal relay is more cost-effective to use than self-resetting thermal relays, as there is no need to purchase and replace fuses.

Manual reset-ready thermal relays are used in a variety of applications, including:

Industrial electric motors
Commercial electric motors
Residential electric motors
Electrical equipment
Thermal relays designed for manual reset are an important component for the protection of electric motors. By choosing the right thermal relays for your applications, you can protect your motors from damage and ensure their life.
