MU1-B-34-612-1-A21-B-E Description

Short technical summary and product information.

The Littelfuse MU1-B-34-612-1-A21-B-E is a magnetic circuit breaker featuring a hydraulic delay trip mechanism. It is rated for a continuous current of 12A and a voltage of 250V.

 

This breaker type uses a magnetic coil with a hydraulic delay to provide time-delayed overcurrent protection. The hydraulic delay allows the breaker to tolerate temporary inrush currents without nuisance tripping, making it suitable for applications with inductive loads.

 

The part is designed for panel mount installation and is commonly used in industrial control, power distribution, and equipment protection applications.
