ZB12-16 Eaton Overload Relay

The Moeller ZB12-16 is a thermal overload relay for industrial motor protection, with an adjustable current range of 12–16A. Its 3P configuration and adjustable overload range suit motor protection applications. One normally open and one normally closed auxiliary contact support straightforward integration into motor control circuits. In contrast to lower-rated models, the ZB12-16 does not specify fuse or circuit breaker ratings for short-circuit protection at 600 VAC; no such ratings should be inferred. The relay is certified to UL, CSA, and IEC standards. It combines adjustable thermal overload protection with auxiliary contact functions for motor protection and control circuits.
