ETA Thermal Circuit Breaker 1A Current Rating 5-Pole Screw Terminal Rocker Actuator 3120-N551-H7T1-W02D-1A

ETA 3120-N551-H7T1-W02D-1A thermal circuit breaker is a 5-pole device designed for overload protection and switching functions in one compact unit. It integrates a thermal bimetal trip element with a rocker-style reset actuator, allowing reliable and quick manual resetting after an overload event.

This circuit breaker features a positively trip-free mechanism that disconnects the circuit reliably, even if the actuator is blocked, enhancing electrical safety. It uses blade terminals with flat head M3.5 screws ensuring secure electrical connections, especially when used with an under voltage release module.

The snap-in mounting design with cut-out size 44.5mm by 22mm allows fast and space-efficient installation in electrical panels. Its rated voltage is 240V AC and 50V DC with a breaking capacity of 1A, suitable for many industrial and commercial electrical applications.

The device is compliant with numerous international standards including REACH, RoHS, VDE, IEC, CSA, EAC, and CCC, ensuring reliable performance and regulatory acceptance across different regions.

Its compact dimensions (25mm width, 52.4mm height, 42.6mm depth) reduce panel space usage and lower wiring and mounting time. This Thermal Circuit Breaker is ideal for protecting motors, pumps, transformers, and cables from overload conditions in construction, industrial automation, HVAC, and manufacturing environments.
