ETA 3120-N Series Thermal Circuit Breaker 15A Current Rating 2-Pole Screw Mount 240V AC 50V DC 3120-N521-H7T1-W01D-15A-U0000M

ETA 3120-N521-H7T1-W01D-15A-U0000M is a 2-pole thermal circuit breaker combining overcurrent protection and an ON/OFF switch within a single compact component. It is specially designed for industrial and commercial applications requiring reliable overload protection of electrical loads including motors, pumps, transformers, and cables. The device operates on a thermal bimetal tripping mechanism, providing dependable protection against thermal overloads.

The device accommodates blade terminals with flat head screws M3.5 suitable for units equipped with an undervoltage release module. After a trip event, the circuit breaker can be reset easily and quickly through its rocker actuator, improving operational uptime.

The positively trip-free feature guarantees that the circuit is reliably disconnected even if the actuator is held in the ON position, enhancing safety for maintenance personnel and equipment. It supports rated voltages of 240V AC and 50V DC, suitable for a variety of industrial and electrical automation systems.

The compact 25mm width design along with snap-in mounting using a 44.5 x 22mm cut-out minimizes required panel space and installation time. The screw mounting and terminal type ensure secure and stable electrical connections, while a power-on protection and water splash cover improve long term durability and environmental resistance.

This thermal circuit breaker adheres to multiple international standards including IEC, VDE, REACH, CSA, RoHS, EAC, and CCC, ensuring compliance with regulatory requirements for safety, reliability, and environmental impact.

The circuit breaker is manufactured in Tunisia under stringent quality controls assuring consistent performance for industrial, laboratory, HVAC, manufacturing, and water treatment applications. Its space-saving and modular design enables convenient integration in control panels, reducing inventory and storage complexities.
