The E-T-A 3120-N501-G7Q1-W14DR3-20A is a thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. It utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables. This 2-pole breaker has a 20A current rating and a 415V voltage rating.
Designed for panel mounting with a rocker actuator, this circuit breaker offers reliable disconnection even with a blocked actuator due to its positively trip-free mechanism. It can be easily and quickly reset after tripping. The illumination is red and operates at a nominal voltage of 115V.
Typical applications 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 C22.2 No 235, GB 17701, IEC 60934, and UL1077.
The datasheet indicates an internal resistance of less than 0.02 Ohm at 20A and typical life cycles of 30,000 for single pole and 50,000 for double pole under specific inductive load conditions.
