Product Description
ETA 3120-N521-H7T1-W01D-20A-U0000M is a high-quality 2-pole thermal circuit breaker designed to provide dependable overload protection and switch functionality in one compact device. Operating with a 20A current rating, this breaker supports both AC (240V) and DC (50V) circuits, making it versatile for various electrical applications.
The device employs a thermal bimetal trip element that responds accurately to overload conditions and quickly trips the circuit to prevent damage. After tripping, it can be reset easily using the rocker actuator, which is ergonomically designed for repeated manual engagement.
Its snap-in mounting system fits cut-outs of 44.5 x 22mm and features blade terminals secured by flat head M3.5 screws for firm connections with wiring. The compact dimensions of 52.4mm in height, 25mm width, and 42.6mm depth ensure efficient panel space utilization, while the positively trip-free mechanism ensures safe and reliable circuit disconnection even if the actuator is blocked.
This circuit breaker meets multiple international standards including IEC, RoHS, CCC, EAC, CSA, REACH, and VDE, confirming its quality and compliance. It is ideally suited to protect motors, pumps, transformers, and cables from overload in industrial, commercial, and automation installations.
Additional benefits include reduced mounting and wiring time, power-on protection with water splash cover, space-saving design, and enhanced overall reliability. The snap-in mounting fits cut-outs sized 44.5 x 22mm for quick installation.
It features a rocker reset actuator ensuring easy and fast manual reset after tripping. Blade terminals with flat head M3.5 screws provide secure wiring connections. Designed for rated AC voltage of 240V and DC voltage of 50V with a breaking capacity of 20A.
