The E-T-A 3120-N321-P7T1-W19LG4-3A is a thermal circuit breaker and switch combination, offering both overcurrent protection and ON/OFF functionality. It is a double-pole device with a 3A current rating and supports a voltage rating of 415V AC and 50V DC.
This circuit breaker is suitable for overload protection of motors, pumps, transformers, and cables. It features a rocker actuator for manual operation and a panel mount design for easy integration into equipment. The thermal trip element ensures reliable disconnection of the circuit, and the positively trip-free mechanism guarantees disconnection even with a blocked actuator.
Typical applications for this series include medical and laboratory equipment, apparatus and machine construction, professional tools, and household appliances. The device is approved by CSA, GB, IEC, and UL standards.
