3120-F321-P7T1-W01D-X3120-M2P7M-240V-20A Description

Short technical summary and product information.

The E-T-A 3120-N series circuit breaker combines protection and switching in a single component, reducing mounting and wiring time. This thermal circuit breaker features a bimetal strip tripping element, offering optimal overload protection and tolerating inrush current peaks from motors and transformers.

 

With a 20A current rating and a 250V voltage rating, this 2-pole breaker is designed for panel mounting and utilizes a rocker actuator. It is approved by CSA, GB, IEC, and UL standards. The 3120-N series eliminates the need for fuse replacement, as it can be easily reset after tripping due to overcurrent.

 

This space-saving design is ideal for applications where reliability and cost-effectiveness are important. The rocker actuation is available with various options, and add-on modules for undervoltage release, magnetic trip, remote trip, and auxiliary contacts are also available, providing solutions for challenging applications.
