MA1-B-30-450-1-A22-B-C Description

Short technical summary and product information.

This Littelfuse circuit breaker is a single-pole, hydraulic-magnetic type rated at 5A continuous current and 250V. It uses a magnetic trip mechanism with hydraulic damping to provide time-delay overcurrent protection, allowing for inrush currents while maintaining fast response to short circuits.

 

The non-illuminated rocker actuator enables simple manual reset and control. The breaker is designed for panel mount installation, offering a compact solution for overcurrent protection in various applications. It holds approvals from CCC, CSA, and UL1077, indicating compliance with multiple international standards.

 

Typical applications include power distribution panels, industrial equipment, and machinery control circuits where reliable circuit protection is required. The hydraulic-magnetic design ensures stable performance across a wide range of ambient temperatures, making it suitable for demanding environments.
