The E-T-A 3120-N321-P7T1-W14FR1-16A is a two-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. The breaker can be reliably reset after tripping.
Key electrical specifications include a voltage rating of 415V AC and a current rating of 16A. It has a typical internal resistance of less than 0.02 Ω per pole at 16A. The typical life expectancy for a two-pole configuration at AC 240V and 16A is 50,000 cycles.
This circuit breaker is designed for panel mounting and features a rocker actuator. It also includes red illumination with a nominal voltage of 12V. The device is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.
Typical applications for this type of thermal circuit breaker include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, and audio equipment.
