3120-F31A-H7T1-W12LY3-2.5A Description

Short technical summary and product information.

The E-T-A 3120-F31A-H7T1-W12LY3-2.5A is a thermal circuit breaker designed for reliable overcurrent protection and switching in a single component. This single-pole breaker features a rocker actuator and is suitable for panel mounting.

 

With a current rating of 2.5A and voltage ratings of 250VAC and 50VDC, this circuit breaker utilizes a bimetal trip element. This bimetal element provides optimal overload protection and can tolerate inrush current peaks from motors and transformers. The trip time is influenced by the overcurrent's peak and duration, as well as the ambient temperature.

 

The 3120-N series circuit breakers eliminate the need for fuse replacement, as they can be easily reset after tripping. This reduces mounting and wiring time by consolidating the functions of a switch, fuse holder, and fuse into one unit. The space-saving design makes it suitable for applications with limited space.

 

This circuit breaker is approved by CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, ensuring compliance with various safety standards. It is designed for enhanced reliability, minimizing potential sources of error in electrical systems.
