ETA Thermal Circuit Breaker 2-Pole 12A Screw Mount with Rocker Reset Actuator 3120-N521-H7T1-W01D-12A

The ETA 3120-N521-H7T1-W01D-12A is a high-quality thermal circuit breaker designed for industrial and commercial electrical applications. It integrates overcurrent protection with an ON/OFF switch capability in a single compact component.

Featuring a 12 ampere current rating and a dual pole configuration, this breaker is engineered for use in circuits operating up to 240V AC and 50V DC. The thermal tripping mechanism utilizes a reliable thermal bimetal element that triggers the breaker in the event of overload, ensuring circuit protection and operator safety.

Resetting the breaker is simple and fast, thanks to its rocker type actuator. The positively trip-free mechanism guarantees disconnection even if the actuator is blocked, preventing hazardous failures. This makes it especially suited for guarding motors, pumps, transformers, and cable circuits against overload damage.

It comes with a screw terminal type mounting and snap-in installation for quick fitting in panel boards with a 44.5 x 22 mm cut-out. The physical dimensions are optimized for compactness: 25 mm width, 52.4 mm height, and 42.6 mm depth, enabling efficient use of space in electrical enclosures.

The product complies with multiple international standards and approvals including CCC, VDE, CSA, RoHS, EAC, REACH, and IEC, underscoring its quality and safety certifications. The blade terminals use flat head M3.5 screws suitable for units with under voltage release modules.

Manufactured in Tunisia, this thermal circuit breaker combines durability with reliable electrical performance. It reduces wiring and mounting time, lowers storage costs through space-saving design, and increases overall reliability of electrical protection systems in industrial, commercial, and automation settings.
