ZB12-10 Eaton Overload Relay

The ZB12-10 is a Moeller thermal overload relay intended to protect motors with operating currents within an adjustable 6–10A range. Its 3P configuration supports three-phase motor protection, while one normally open and one normally closed auxiliary contact provide integration points for motor control circuits. A 40A fuse or 25A circuit breaker safeguards the relay for short-circuit events up to 600 VAC. The overload relay carries UL, CSA, and IEC approvals, making it suitable for industrial motor protection applications requiring coordination with the specified short-circuit protective devices in motor control systems.
