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

ETA 3120-N551-H7T1-W02D-5A thermal circuit breaker is a high-quality protective device designed with a 5-pole configuration and a 5A current rating to provide reliable overcurrent protection and switching function in a single compact unit.

This thermal rocker actuated breaker combines the function of an ON/OFF switch with overload protection, making it suitable for industrial and commercial electrical applications. It utilizes a thermal bimetal trip element which reacts to excessive current by tripping reliably and can be quickly reset via the rocker actuator.

The device is engineered with screw-type blade terminals fixed with M3.5 flat head screws ensuring secure wiring connections. It also features a positively trip-free design, ensuring that the breaker disconnects the circuit safely even if the actuator is blocked manually, enhancing safety.

With a snap-in mounting system for panels featuring a cut-out size of 44.5mm x 22mm and compact dimensions of 25mm width, 52.4mm height, and 42.6mm depth, the breaker is easy to install and space-efficient.

Designed to operate at rated voltages of 240V AC and 50V DC, the breaker supports a breaking capacity of 5A and is in compliance with several international standards such as VDE, CCC, CSA, REACH, RoHS, EAC, and IEC, assuring quality and regulatory adherence.

This circuit breaker is ideal for protecting motors, pumps, transformers, and electrical cables against overload conditions in various industrial, manufacturing, commercial, and HVAC electrical systems.

The breaker provides overcurrent protection combined with reliable ON/OFF switching. Thermal tripping mechanism with rocker reset actuator enhances safety and usability. Mounting and wiring are simplified through snap-in mounting and screw terminals.

Compact design saves installation space and reduces storage costs. Meets strict international electrical standards ensuring broad application compatibility. Positive trip-free operation guarantees circuit disconnection under fault conditions.

Suitable for motor and pump overload protection, transformer safeguarding, and cable protection. Constructed for use in industrial, commercial, manufacturing, and water treatment electrical systems. Package includes the ETA 3120-N Thermal Circuit Breaker with all required terminal screws.
