ABB Thermal Overload Relay 24V DC

The ABB Thermal Overload Relay (24V DC) is an electromechanical protection device designed for the main electrical circuit, primarily used to protect motors from overload and phase failure. Key features and specifications include:

• Protection Function: Reliable and fast protection for motors in the event of overload or phase failure. It utilizes bimetal tripping elements that react to excess current by bending, causing the relay to trip and change the contact positions.

• Reset Options: Supports both manual and automatic reset selection, giving flexibility in operation and maintenance.

• Auxiliary Contacts: Typically provides two auxiliary contacts, one normally open (N.O.) and one normally closed (N.C.), which can be used for signaling and integrating with control circuits.
