3120-F321-H7M1-W01F-16A Description

Short technical summary and product information.

The E-T-A 3120-F321-H7M1-W01F-16A is a thermal circuit breaker from the 3120-N series, designed for reliable overcurrent protection and switching in a single component. This 2-pole breaker features a rocker actuator and is suitable for panel mounting.

 

Key electrical specifications include a current rating of 16A and a voltage rating of 250V AC. It also has a DC voltage rating of 50V. The breaker type is thermal, utilizing a bimetal strip for tripping, which tolerates inrush current peaks and trips faster at high ambient temperatures. It is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.

 

This circuit breaker eliminates the need for fuse replacement, as it can be easily reset after tripping. Its design reduces mounting and wiring time by integrating switch and fuse functions into one component. The space-saving design makes it suitable for constricted areas. The RoHS status is RoHS3 Compliant, MSL is 1 Unlimited, and REACH status is REACH Unaffected.
