MG1-B-34-440-1-FB3-B-C Description

Short technical summary and product information.

The Littelfuse MG1-B-34-440-1-FB3-B-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in a variety of applications. It is rated for 4A continuous current at 250V AC/DC, providing reliable circuit interruption under fault conditions.

 

The breaker utilizes a magnetic (hydraulic delay) trip mechanism, which offers predictable time-current characteristics and is less sensitive to ambient temperature changes compared to thermal breakers. The actuator is a rocker type with red illumination, operating at a nominal voltage of 9 to 16V, providing clear visual indication of the breaker state.

 

This component is designed for panel mount installation, making it suitable for use in control panels, power distribution units, and industrial equipment where a robust, manually resettable overcurrent protector is required.
