The E-T-A 3120-N511-P7T1-W14LR3-20A is a single-pole thermal circuit breaker that combines overcurrent protection with ON/OFF switch functionality. It utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables.
This circuit breaker has a rated voltage of 240 VAC and 50 VDC, with a current rating of 20A. It offers a current rating range from 0.1 to 20A. The device is designed for panel mounting and features a rocker actuator. It also includes illumination with a nominal voltage of 115V.
Key features include a positively trip-free mechanism for reliable disconnection, even with a blocked actuator. It is designed for easy and quick resetting after tripping. The typical life for a single-pole unit is 30,000 cycles at 1x IN, inductive.
Typical applications for this series include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
