The Moeller ZB150-70/KK is a 3P thermal overload relay for motor protection, with an adjustable current range of 50–70A. It provides one normally open and one normally closed auxiliary contact for integration into motor control systems. For short-circuit protection up to 600 VAC, the relay can be used with a 250A fuse or a 250A circuit breaker. Its UL, CSA, and IEC certifications indicate compliance with recognized electrical standards for industrial motor applications. The ZB150-70/KK is designed for heavy-duty industrial motor protection, where the adjustable overload setting and auxiliary contacts support integration with motor protection and control equipment.
