ETA 3120-N Thermal Circuit Breaker 5A Current Rating 5-Pole Screw Mount 240V AC 50V DC 3120-N551-H7T1-W14DR4-5A

ETA 3120-N551-H7T1-W14DR4-5A Thermal Circuit Breaker is a robust and compact 5-pole electrical protection device designed for thermal overload and switching applications. It integrates overcurrent protection with a convenient ON/OFF rocker switch mechanism for easy control.

The device features blade terminals secured by flat head M3.5 screws, suitable for units with an undervoltage release module. The thermal bimetal trip element offers reliable and fast response to overload conditions. After tripping, the breaker can be promptly and safely reset using the rocker actuator.

This thermal circuit breaker has a positively trip-free mechanism, which ensures that the circuit is disconnected reliably even if the actuator is obstructed or blocked. Electrical ratings include a 5A current strength, 240V AC rated voltage, and 50V DC rated voltage with a 5A breaking capacity, making it suitable for diverse electrical industrial and commercial systems.

Its compact design, with dimensions of 25mm width, 52.4mm height, and 42.6mm depth, supports snap-in mounting via a cut-out of 44.5mm by 22mm, contributing to reduced wiring and installation time. The screw mount type with screw terminals ensures secure and robust connections.

Compliance with multiple international standards such as EAC, CSA, REACH, RoHS, VDE, CCC, and IEC affirms its quality and suitability for electrical safety requirements. The Thermal Circuit Breaker is primarily used for overload protection of motors, pumps, transformers, and cables in industrial, commercial, and residential electrical panels.
