The E-T-A 3120-N series thermal circuit breaker, part number 3120-N32V-H7T1-SGRX-X3120-U0100M-4A, combines overcurrent protection with an ON/OFF switch function. This 2-pole device utilizes a thermal-bimetal trip element and is rated for 4A at 415V AC.
Designed for overload protection of motors, pumps, transformers, and cables, this circuit breaker can be reliably reset after tripping. It features a positively trip-free mechanism for guaranteed disconnection. The breaker is suitable for panel mounting and offers options for enhanced functionality through add-on modules.
Key electrical specifications include a current rating range from 0.1A to 20A and voltage ratings of AC 240V, DC 50V, and DC 28V. Typical life expectancy is rated at 30,000 cycles under inductive load conditions for single-pole operation and 50,000 cycles for double-pole operation.
Typical applications include medical and laboratory equipment, apparatus and machine construction, professional tools, household appliances, office machines, and audio equipment. It is also suitable for use in medical equipment according to IEC/EN 60601.
