Product Description
The ETA 3120-N521-H7T1-W01D-16A Thermal Circuit Breaker is a 2-pole device designed for circuit protection with an integrated ON/OFF switch function. It uses a thermal bimetal trip element ensuring rapid, reliable response to overload conditions and can be easily reset using the rocker actuator.
This circuit breaker features blade terminals with flat head screws (M3.5) facilitating efficient wiring and the snap-in mounting with a cut-out dimension of 44.5 x 22mm saves installation time and optimizes panel space.
The breaker is suitable for overload protection in industrial and commercial applications including motors, pumps, transformers, and cable circuits. Its positive trip-free mechanism ensures safe disconnection even if the actuator is physically blocked, enhancing safety.
Electrical ratings include a rated AC voltage of 240V and DC voltage of 50V with a breaking capacity of 16A, supporting reliable interruption of overcurrent conditions up to this threshold.
Constructed to meet a wide range of international standards (CSA, EAC, REACH, CCC, IEC, RoHS, VDE), this circuit breaker combines safety, reliability, and ease of use into a compact 25mm wide housing.
