MU1-B-10-450-3-C21-B-C Description

Short technical summary and product information.

The Littelfuse MU1-B-10-450-3-C21-B-C is a single-pole magnetic hydraulic delay circuit breaker rated for 5A at 250V. It features a push-to-reset actuator and is designed for panel mount installation. This breaker is approved by CCC, CSA, and UL1077.

 

The magnetic hydraulic delay mechanism provides a time-delayed trip characteristic, making it suitable for circuits with inrush currents while still providing overcurrent protection. The single-pole configuration is used in branch circuit protection for a variety of equipment.

 

The breaker has no illumination and is supplied in a panel mount package.
