The E-T-A 3120-N321-P7T1-W12FY3-20A is a two-pole thermal circuit breaker that combines overcurrent protection with ON/OFF switch functionality. It features a thermal-bimetal trip element and a positively trip-free mechanism for reliable disconnection. This circuit breaker is rated for a current of 20A and a voltage of 415V, with a panel mount type.
Designed for applications such as motor, pump, transformer, and cable overload protection, it can be easily and quickly reset after tripping. The 3120-N series is suitable for various equipment, including medical and laboratory devices, apparatus and machine construction, professional tools, and household appliances. Its compact design and resettable functionality contribute to increased equipment availability and reduced mounting and wiring time.
Further technical details indicate rated voltages of AC 240V and DC 50V, with a current rating range from 0.1A to 20A. The typical life for a 1-pole configuration is 30,000 cycles under specific conditions, and 50,000 cycles for a 2-pole configuration under AC 240V.
