Industrial ZB12-10 Thermal Overload Relay 6-10A

Description:

The Klockner Moeller ZB12-10 Thermal Overload Relay is an electromechanical motor protection relay used in industrial motor control and starter systems. Commonly installed with DIL and DILM contactors in conveyor systems, pumps, compressors, HVAC equipment, and manufacturing machinery requiring overload and phase-loss protection. Maintenance teams, OEMs, and system integrators use this overload relay for equipment repairs, motor starter retrofits, and replacement of existing overload protection devices.

Applications:

The Klockner Moeller ZB12-10 is designed to provide thermal overload and phase-loss protection for three-phase motors in industrial environments. It is commonly used in motor control centers, conveyor systems, pumping stations, compressors, fans, and manufacturing equipment where reliable motor protection is required to minimize downtime and extend equipment life. The relay mounts directly to Moeller DILM7, DILM9, DILM12, and DILM15 contactors for compact motor starter assemblies.
