The E-T-A 3120-N311-P7T1-W14DR3-4A is a single-pole thermal circuit breaker designed for overcurrent protection and switch functionality. It utilizes a thermal-bimetal trip element and is suitable for protecting motors, pumps, transformers, and cables.
This circuit breaker has a current rating of 4A and a voltage rating of up to 415V AC. It features a rocker actuator for operation and is designed for panel mounting. The device offers reliable disconnection even with a blocked actuator due to its positively trip-free mechanism. It can be easily and quickly reset after tripping.
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. The 3120-N series is also available with thermal-magnetic trip options and can be expanded with add-on modules for enhanced functionality.
Key electrical specifications include a 4A current rating and a 415V AC voltage rating. The internal resistance at 4A is less than 0.02 Ohms. The illumination is red with a nominal voltage of 115V.
