The E-T-A 3120-N321-P7T1-W01D-0.3A is a thermal circuit breaker that combines overcurrent protection with ON/OFF switch functionality in a single component. It utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables.
This two-pole breaker has a current rating of 0.3A and a voltage rating of 415V AC. It is designed for panel mounting and features a rocker actuator. The breaker can be reliably reset after tripping, and its positively trip-free mechanism ensures disconnection even with a blocked actuator.
Key specifications include a current rating range of 0.1A to 20A and typical life cycles of up to 50,000 cycles for two-pole configurations at AC 240V. The device is also suitable for use in medical equipment according to IEC/EN 60601 standards.
Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. Its space-saving design and reduced mounting and wiring time contribute to increased overall reliability and reduced costs.
The circuit breaker is rated for 240VAC and 50VDC.
The continuous current rating is 0.3A.
It is a 2-pole circuit breaker.
It uses a rocker actuator.
Typical life is 30,000 cycles at 1x rated current under inductive load for AC 240V and DC 50V, and 50,000 cycles for 2-pole AC 240V operation.
It is approved to CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
