MT1-B-94-420-1-A21-B-C Description

Short technical summary and product information.

The MT1-B-94-420-1-A21-B-C is a magnetic circuit breaker from Littelfuse designed for overcurrent protection in electrical systems. Its magnetic hydraulic delay mechanism provides predictable trip behavior across a range of fault conditions.

 

This breaker is rated for 2A continuous current at 250V and is configured as a single-pole device. The push-pull actuator supports simple manual control, while the panel mount package allows installation into standard panel openings.

 

The part is non-illuminated and does not require external illumination circuitry. Magnetic hydraulic delay breakers are commonly used in applications where ambient temperature stability and precise overcurrent protection are required. The panel mount design and push-pull actuation make it suitable for front-panel control and reset operations.
