MD1-B-34-250-1-A36-A-C Description

Short technical summary and product information.

The Littelfuse MD1-B-34-250-1-A36-A-C is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection. It is rated for 500mA continuous current at 250V AC/DC, providing reliable circuit interruption under fault conditions.

 

The breaker uses a magnetic hydraulic delay mechanism, which offers precise trip characteristics and is less sensitive to ambient temperature changes compared to thermal breakers. The rocker actuator provides a clear on/off indication and manual reset capability.

 

This circuit breaker is panel mounted, making it suitable for integration into control panels, power distribution units, and industrial equipment. It holds approvals from CCC, CSA, and UL1077, indicating compliance with international safety standards.
