3120-N521-H7T1-W02L-20A Description

Short technical summary and product information.

The E-T-A 3120-N521-H7T1-W02L-20A is a two-pole thermal circuit breaker that combines overcurrent protection with an ON/OFF switch function. It is rated for 20A and operates at 240 VAC or 50 VDC, with an option for 415 VAC upon request. The breaker utilizes a thermal-bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables.

 

Designed for easy integration, this circuit breaker features a panel mount configuration and a rocker actuator. Its positively trip-free mechanism ensures reliable disconnection even when the actuator is blocked. The 3120-N series offers expandable functionality through various add-on modules and is suitable for use in medical equipment according to IEC/EN 60601.

 

Key features include its ability to be reliably reset after tripping, reduced mounting and wiring time due to its space-saving design, and increased overall reliability. The current rating range is from 0.1A to 20A, with options for higher ratings available upon request. Approval agencies include CSA, KTL, UL, and VDE.
