The E-T-A 3120-N31F-P7T1-SGRD-15A 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 for reliable overload protection of motors, pumps, transformers, and cables.
This circuit breaker has a current rating of 15A and a voltage rating of 415V. It is designed for panel mounting and features a pushbutton actuator. The device can be easily and quickly reset after tripping, and its positively trip-free mechanism ensures reliable disconnection even with a blocked actuator.
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 suitable for use in medical equipment according to IEC/EN 60601.
The datasheet indicates additional voltage ratings of AC 240V and DC 50V, with a current rating range from 0.1A to 20A. Typical life cycles are rated at 30,000 for 1-pole configurations under specific conditions.
