The E-T-A 3120-N521-P7T1-W19LG4-16A 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 easily and quickly reset after tripping, and its positively trip-free mechanism ensures reliable disconnection even with a blocked actuator.
This model features a 16A current rating and a voltage rating of up to 415V AC. It is designed for panel mounting and has a rocker actuator. The illumination is green with a nominal voltage of 230V. The circuit breaker is approved by CSA, GB, IEC, and UL standards.
Typical applications for this series include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools. The device offers features such as quick resettability and a space-saving design, contributing to increased overall reliability and reduced mounting and wiring time.
The circuit breaker is rated for 240V AC and 50V DC.
The breaker is rated for 16A with an operating range of 0.1 to 20A.
It is a thermal circuit breaker.
It is a 2-pole circuit breaker.
