ETA Thermal Circuit Breaker 3A Current Rating 5-Pole Screw Mount 240V AC 50V DC Rocker Actuator 3120-N551-H7T1-W02D-3A

The ETA 3120-N551-H7T1-W02D-3A thermal circuit breaker is a 5-pole device designed for reliable overload protection in industrial and commercial electrical systems. It integrates overcurrent protection with an ON/OFF switch functionality using a rocker actuator for easy manual resetting.

Engineered with a thermal bimetal trip element, this breaker reacts to continuous overloads by tripping and isolating the electrical circuit, then allows swift restoration by manual reset. Its positively trip-free mechanism ensures the circuit disconnects safely even if the actuator is obstructed, providing enhanced operator safety.

Rated for 3A current with 240V AC and 50V DC voltages, it supports a wide range of applications including motors, pumps, transformers, and cable protection. The snap-in mounting with a cut-out dimension of 44.5mm x 22mm coupled with screw terminals and blade connectors makes installation straightforward and secure.

Measuring 52.4mm in height, 25mm in width, and 42.6mm in depth, this compact breaker saves panel space and reduces wiring efforts. Its compliance with multiple international standards such as CSA, IEC, VDE, EAC, RoHS, CCC, and REACH ensures suitability for global markets and industrial environments.
