This E-T-A 3120-N thermal circuit breaker 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 positively trip-free mechanism ensures reliable disconnection.
Key electrical specifications include a 5A current rating and a 415V voltage rating. This 2-pole unit is designed for panel mounting and features a pushbutton actuator. The internal resistance per pole is less than 0.02 Ohms.
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 approved by CSA, GB, IEC, and UL standards.
The breaker can be easily and quickly reset after tripping. Optional features and functional extensions are available through add-on modules, though not specified for this particular part number.
