The LS Thermal Overload Relay MT-45–65A is a high-performance motor protection device engineered to safeguard electric motors against overload conditions. Designed for use with LS MC-50A, MC-55A, and MC-65A contactors, this relay provides precise thermal protection in the 45A to 65A operating current range. It is ideal for industrial automation systems, motor control panels, and heavy-duty electrical installations.

This thermal overload relay helps prevent costly equipment failure by accurately detecting excess heat and automatically disconnecting power during overloads. Its compact design, adjustable trip settings, and compatibility with LS contactors make it a reliable solution for motor circuit protection.
