MU1-B-10-625-2-A21-B-C Description

Short technical summary and product information.

The Littelfuse MU1-B-10-625-2-A21-B-C is a single-pole magnetic circuit breaker employing hydraulic delay technology. It is rated for 25A continuous current at 250V. The breaker utilizes a push-to-reset actuator for manual reset after a trip event.

 

This circuit breaker is designed for panel mount installation, making it suitable for a variety of industrial and commercial applications. It carries approvals from UL1077, CSA, and CCC, ensuring compliance with international safety standards. The non-illuminated design simplifies integration into existing control panels.

 

With its magnetic hydraulic delay mechanism, the breaker provides reliable overcurrent protection with time-delay characteristics, accommodating temporary inrush currents without nuisance tripping. It is an ideal choice for protecting branch circuits, power supplies, and equipment.
