This E-T-A 3120-N321-P7T1-W12DY4-8A is a thermal circuit breaker designed for overcurrent protection and switch functionality. It operates with a current rating of 8A and a voltage rating of 415V AC, featuring two poles for circuit interruption.
The breaker utilizes a thermal bimetal trip element and offers a positively trip-free mechanism for reliable disconnection. It is suitable for panel mounting and includes a rocker actuator for operation. The illumination is white with a nominal voltage of 230V.
Typical applications for this type of circuit breaker include overload protection for motors, pumps, transformers, and cables in various industrial and commercial equipment. Its resettable design ensures quick restoration of power after a trip event, minimizing downtime.
Key specifications include a typical life of 30,000 cycles for single-pole configurations and 50,000 cycles for double-pole configurations under specific load conditions. The internal resistance per pole varies with the current rating, as detailed in the manufacturer's datasheet.
