This E-T-A 3120-N351-H7T1-W14DR4-20A is a thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. It is a 2-pole device rated for 415V AC and 20A.
The breaker utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables. It features a positively trip-free mechanism for reliable disconnection, even with a blocked actuator. The unit can be easily and quickly reset after tripping.
Designed for panel mounting with a rocker actuator, this circuit breaker also includes red illumination for 230V nominal voltage. Its typical internal resistance at 20A is less than 0.02 Ohm. The device is approved by CSA, GB, IEC, and UL standards.
Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
