MF1-B-20-620-2-DB3-B-C Description

Short technical summary and product information.

The Littelfuse MF1-B-20-620-2-DB3-B-C is a single-pole magnetic (hydraulic delay) circuit breaker designed for panel mount applications. It is rated for 20A continuous current at 250V AC/DC, providing reliable overcurrent protection in a compact form factor.

 

The circuit breaker features a red illumination indicator that offers visual status of the breaker state. The hydraulic delay mechanism allows for precise time-current characteristics, making it suitable for applications where inrush currents or short overloads must be tolerated without nuisance tripping.

 

This component is approved by CCC, CSA, and UL1077, ensuring compliance with international safety standards for industrial and commercial equipment. The panel mount design simplifies integration into control panels, power distribution units, and other electrical assemblies.
