The E-T-A 3120-N551-P7T1-W01D-8A 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.
This panel mount circuit breaker features a rocker actuator and a voltage rating of 415V AC. It has a current rating of 8A and an internal resistance of less than 0.02 Ohms per pole. The typical life for this device is rated at 30,000 cycles at 1 x IN, inductive.
Key features include its positively trip-free mechanism for reliable disconnection, even with a blocked actuator. The 3120-N series is also available with thermal-magnetic trip options and can be expanded with add-on modules for enhanced functionality. It is suitable for use in medical equipment according to IEC/EN 60601 standards.
Typical applications for this thermal circuit breaker include medical and laboratory equipment, apparatus and machine construction, professional tools, household and garden appliances, office machines, audio equipment, and machine tools.
