Overload Relay Z0-2,1-NA - 1.2A to 2.1A - KLOCKNER MOELLER Z0

Description:

The Klockner Moeller Z0-2,1-NA Thermal Overload Relay is an electromechanical motor protection relay used in industrial motor control and starter systems. Commonly installed with DIL and DILE contactors in conveyor systems, pumps, compressors, HVAC equipment, and manufacturing machinery requiring overload and phase-failure 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 Z0-2,1-NA is designed to provide thermal overload and phase-failure 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 DIL0 and DILEM contactors to create compact motor starter assemblies.
