MA1-B-24-480-1-A14-B-D Description

Short technical summary and product information.

The Littelfuse MA1-B-24-480-1-A14-B-D is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in a variety of applications. It is rated for 8A continuous current at 250V AC/DC.

 

This breaker employs a magnetic (hydraulic delay) trip mechanism, which provides time-delayed response to inrush currents while ensuring fast tripping on high fault currents. The rocker actuator allows for manual reset and is non-illuminated.

 

Panel-mount installation enables direct integration into control panels, power distribution units, and industrial equipment. The breaker is certified by major safety agencies including UL, CSA, VDE, and CCC, ensuring compliance with global standards.

 

Typical uses include motor protection, power supply protection, and general circuit protection in commercial and industrial environments.
