MA1-B-34-475-1-A17-A-D Description

Short technical summary and product information.

The Littelfuse MA1-B-34-475-1-A17-A-D is a single-pole magnetic circuit breaker utilizing a hydraulic delay mechanism for reliable overcurrent protection. It is rated for 7.5A continuous current at 250V AC/DC, making it suitable for a variety of power distribution and equipment protection applications.

 

The breaker employs a rocker actuator for manual on/off control and is designed for panel mounting. The magnetic hydraulic delay design provides predictable time-current trip characteristics, offering protection against short circuits and sustained overloads without nuisance tripping from transient inrush currents.

 

This component carries approvals from CCC, CSA, UL, and VDE, indicating compliance with major international safety standards. It is a non-illuminated device, suitable for applications where visual indication of breaker state is not required.
