ZB150-35/KK Eaton Overload Relay

The Moeller ZB150-35/KK is a thermal overload relay for motor protection, with an adjustable current range of 25–35A and a 3P configuration. Its auxiliary contact arrangement includes one normally open and one normally closed contact, allowing integration into motor control systems. For short-circuit protection up to 600 VAC, the relay may be paired with a 125A fuse or a 125A circuit breaker. The 25–35A adjustment supports overload protection across the stated motor-current range, while the 3P format provides the specified three-pole arrangement. The relay is certified to UL, CSA, and IEC standards for industrial motor-control applications.
