This E-T-A 3120-N series thermal circuit breaker, part number 3120-N321-P7T1-W01D-X3120-M2P7M-240V-20A, offers reliable overcurrent protection and switch functionality in a single component. It is a two-pole device with a thermal trip element, suitable for protecting motors, pumps, transformers, and cables from overload conditions.
The breaker has a current rating of 20A and a voltage rating of up to 415V AC or 50V DC. It is designed for panel mounting and features a rocker actuator for operation. The positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.
Key specifications include a 20A current rating and a 415V AC voltage rating, with options for DC voltage up to 50V. The device is built for durability, with typical life cycles specified for various voltage and load conditions. Its thermal-magnetic trip capability (available on other variants) and quick resettability contribute to maximum equipment availability.
Typical applications for this series include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment. It is also suitable for use in medical equipment according to IEC/EN 60601 standards.
