ZB32-4 Eaton Overload Relay

The Moeller ZB32-4 is a 3P thermal overload relay designed to protect motors operating within an adjustable current range of 2.4–4A. Built-in overload protection supports motor protection, while one normally open and one normally closed auxiliary contact enable integration into motor control systems. For short-circuit protection at up to 600 VAC, the ZB32-4 can be paired with a 15A fuse or a 25A circuit breaker. UL, CSA, and IEC certifications indicate that the device meets these applicable standards. This overload relay combines current-range adjustment, built-in overload protection, and auxiliary contacts within a single component for motor protection in industrial applications.
