The E-T-A 3120-N321-P7T1-W12DY3-20A is a thermal circuit breaker that combines overcurrent protection with the functionality of an ON/OFF switch. It utilizes a bimetal trip element for reliable operation.
This two-pole breaker is rated for a current of 20A and a voltage of 415V. It features a panel mount design with a rocker actuator and white illumination for status indication at 115V.
Key applications include overload protection for motors, pumps, transformers, and cables. The positively trip-free mechanism ensures reliable disconnection even with a blocked actuator. It is suitable for use in medical equipment according to IEC/EN 60601.
With a focus on equipment availability, this circuit breaker offers overload protection matched to loads, preventing nuisance tripping, and quick resettability. Its space-saving design and reduced mounting/wiring time contribute to increased overall reliability and reduced costs.
The voltage rating is 415V AC, 240V AC, 50V DC, and 28V DC.
The current rating is 20A.
This circuit breaker has 2 poles.
It is a thermal circuit breaker.
The mounting type is Panel Mount.
Approval agencies include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
The RoHS status is RoHS3 Compliant.
