MD1-B-64-625-1-A46-B-C Description

Short technical summary and product information.

The Littelfuse MD1-B-64-625-1-A46-B-C is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in a variety of applications. It is rated for 25 amps at 250 volts AC or 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 easy manual reset. This unit is panel mounted, making it suitable for integration into control panels, power distribution units, and industrial equipment.

 

The component carries approvals from CCC, CSA, and UL1077, indicating compliance with international safety standards for supplementary protectors. It is a non-illuminated, single-pole device, suitable for protecting individual circuits.
