MU2-B-34-613-1-A21-B-C Description

Short technical summary and product information.

The Littelfuse MU2-B-34-613-1-A21-B-C is a hydraulic-magnetic circuit breaker designed for overcurrent protection in electrical circuits. It is a 2-pole device rated for 13A continuous current at 250V AC/DC. The magnetic hydraulic delay mechanism provides reliable trip characteristics with time delay to handle inrush currents without nuisance tripping.

 

The breaker features a panel mount design with push-to-reset actuator. It is non-illuminated. The unit is approved by CCC, CSA, and UL1077, ensuring compliance with international safety standards.

 

This circuit breaker is suitable for use in power distribution, industrial control panels, and equipment requiring reliable overcurrent protection. The 2-pole configuration allows simultaneous disconnection of both live and neutral lines in single-phase systems or can be used in DC applications.
