3120-N321-P7T1-W02D-20A Description

Short technical summary and product information.

The E-T-A 3120-N321-P7T1-W02D-20A is a thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a bimetal trip element for reliable operation.

 

This two-pole breaker is rated for 20A and can handle voltages up to 250VAC or 50VDC. It is designed for panel mounting and features a rocker actuator. The internal resistance at 20A is less than 0.02 Ohms.

 

Typical applications for this series include overload protection of motors, pumps, transformers, and cables. It is suitable for use in medical equipment according to IEC/EN 60601. The positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked.

 

With a typical life of 30,000 cycles at 1x IN under inductive load for DC 28V, and 50,000 cycles for AC 240V, this circuit breaker offers durability and quick resettability for maximum equipment availability.
