The ETA 3120-N 5-pole thermal rocker actuated circuit breaker/switch combination unites overcurrent protection and the function of an ON/OFF switch within a single component. It has blade terminals with flat head screws M3.5 for units with under voltage release module. The trip element is a thermal bimetal. After tripping, it can reliably, easily and quickly be reset. The positively trip-free mechanism ensures reliable disconnection of the circuit even with the actuator blocked. It is ideally suited for overload protection of motors, pumps, transformers and cables.
