MU1-B-94-610-1-A21-B-E Description

Short technical summary and product information.

The Littelfuse MU1-B-94-610-1-A21-B-E is a magnetic hydraulic delay circuit breaker designed for overcurrent protection in electrical circuits. It is rated for 10A continuous current at 250V AC/DC, making it suitable for a variety of industrial and commercial applications.

The breaker features a single pole configuration and a push-to-reset actuator, allowing manual reset after a trip event. The hydraulic delay mechanism provides time-delayed tripping, which helps prevent nuisance tripping from inrush currents while still protecting against sustained overloads and short circuits.

The unit is panel mounted with a standard cutout and includes approvals from CCC, CSA, TUV, and UL, ensuring compliance with international safety standards. The non-illuminated design is straightforward and reliable for basic circuit protection needs.
