ETA 3120-N 5-Pole Thermal Circuit Breaker 10A Current Rating Screw Mount 3120-N551-H7T1-W02D-10A

ETA 3120-N551-H7T1-W02D-10A thermal circuit breaker is a 5-pole, rocker actuated device designed for precise overload and short-circuit protection in electrical circuits. Its trip-free mechanism ensures the circuit disconnects reliably even if the actuating mechanism is blocked, ensuring safety in industrial electrical installations. This thermal breaker incorporates a thermal bimetal trip element that responds efficiently to overcurrent conditions and can be easily reset using the rocker actuator.

The device mounts via a snap-in mechanism into cut-outs measuring 44.5mm by 22mm, simplifying panel integration. Connections are made through screw terminals equipped with flat head M3.5 screws to provide secure and durable wire fixation. The breaker supports AC voltages up to 240V and DC voltages up to 50V, making it suitable for various applications including motor, pump, transformer, and cable protection.

With compact dimensions of 25mm width, 52.4mm height, and 42.6mm depth, this circuit breaker is space-efficient, reducing wiring and mounting times. It complies with multiple international standards including RoHS, CCC, REACH, EAC, VDE, CSA, and IEC, assuring quality and reliability. The breaking capacity is rated at 10A, providing robust protection against fault currents.

Key features include its rocker reset actuator, thermal tripping mechanism, and reliable snap-in mounting, which together form a trusted protective component for industrial, commercial, and electrical automation systems. The circuit breaker is produced in Tunisia and designed for long-term reliable service in demanding environments.
