MU1-B-62-450-1-C21-B-C Description

Short technical summary and product information.

The Littelfuse MU1-B-62-450-1-C21-B-C is a single-pole magnetic circuit breaker featuring hydraulic delay for precise overcurrent protection. It is rated for 5A continuous current at 250V AC/DC, making it suitable for a variety of power distribution and equipment protection applications.

 

The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides time-delayed response to overcurrent conditions. This design helps avoid nuisance tripping from transient surges while ensuring reliable protection against sustained faults. The push-to-reset actuator allows for manual reset after a trip event.

 

This component is intended for panel-mount or equipment-mount installations where a compact, resettable overcurrent protection device is required. Its 1-pole configuration is ideal for single-phase circuits or individual branch protection.
