The E-T-A 3120-N311-P7T1-W01D-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 voltage rating of 415V and a current rating of 4A. It is designed for panel mounting and features a rocker actuator. The device offers reliable disconnection even with a blocked actuator due to its positively trip-free mechanism. After tripping, it can be easily and quickly reset.
Typical applications for this type of circuit breaker include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. It is approved by CSA, GB, IEC, and UL standards.
Further functionality can be expanded through add-on modules for low voltage release, auxiliary contact function, remote trip, or fast magnetic trip. Optional push-in terminals are available for easy and quick wiring.
