The E-T-A 3120-N311-P7T1-W04F-5A is a single-pole thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables.
This circuit breaker features a 5A current rating and a voltage rating of up to 415V AC. It is designed for panel mounting and has 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.
The 3120-N series is also available with thermal-magnetic trip options and as a switch according to EN IEC 61058. Functional extensions are possible with add-on modules for low voltage release, auxiliary contact function, remote trip, or fast magnetic trip.
