MF1-B-34-430-1-BB6-B-C Description

Short technical summary and product information.

The Littelfuse MF1-B-34-430-1-BB6-B-C is a panel-mount circuit breaker intended for overcurrent protection. It is rated for 3A at 250V and uses a magnetic (hydraulic delay) trip mechanism in a single-pole configuration. The breaker is operated with a rocker actuator and includes neon illumination rated at 250V nominal.

The hydraulic-magnetic design combines electromagnetic response with a hydraulic delay element, providing overcurrent protection for panel-mounted circuits up to 250V. The panel mount package and rocker actuator make it suitable for front-panel operation in electrical control and distribution equipment.

Approvals include CCC, CSA, and UL1077. The breaker is classified under Circuit Protection / Circuit Breakers and is available as part number MF1-B-34-430-1-BB6-B-C from Littelfuse Inc.
