ETA Thermal Circuit Breaker 2.5A Current Rating 2-Pole Screw Mount 240V AC 50V DC 3120-N521-H7T1-W01D-2.5A

ETA 3120-N521-H7T1-W01D-2.5A Thermal Circuit Breaker is a high-quality 2-pole circuit breaker designed to provide reliable overcurrent protection combined with on/off switch functionality. Operating at a current rating of 2.5A, this device supports rated voltages of 240V AC and 50V DC, making it suitable for diverse electrical and industrial environments.

The breaker utilizes a thermal bimetal tripping element, ensuring dependable thermal trip response. Its rocker reset actuator allows quick and easy resetting after a trip event without replacement. The positively trip-free mechanism guarantees circuit disconnection even if the actuator is mechanically blocked, ensuring safety and security in operation.

Designed for snap-in mounting with cut-out dimensions of 44.5 x 22mm, the breaker is compact and space-saving, with a width of 25mm, height of 52.4mm, and depth of 42.6mm. Blade terminals fitted with flat-head M3.5 flat head screws secure reliable electrical connections. Enhanced mounting with screw terminals reduces installation and wiring time, providing a robust and efficient setup.

Applications include overload protection for motors, pumps, transformers, and cable circuits in industrial automation, electrical panels, manufacturing, and HVAC systems. The device's compliance with VDE, IEC, RoHS, EAC, CSA, REACH, and CCC standards assures quality, safety, and environmental compliance.

Extended features include power-on protection and water splash cover, further increasing durability in challenging environments. The modular design allows extended functionality through appliance inlet modules and reduces storage and disposition costs.

The device features a thermal tripping mechanism with a rocker reset actuator. Rated AC voltage of 240V and DC voltage of 50V ensures versatile compatibility. Snap-in mounting with cut-out 44.5 x 22mm supports easy installation.
