MD1-B-30-450-1-A15-2-C Description

Short technical summary and product information.

The Littelfuse MD1-B-30-450-1-A15-2-C is a 1-pole magnetic (hydraulic delay) circuit breaker rated at 5A and 250V. It utilizes a rocker actuator for manual on/off control and is designed for panel mount installation. The hydraulic delay mechanism provides time-delayed tripping for handling inrush currents without nuisance tripping, while still offering reliable overcurrent protection. This circuit breaker is approved by CCC, CSA, and UL1077, ensuring compliance with international safety standards. Its non-illuminated design makes it suitable for applications where visual indication is not required. The compact single-pole configuration is ideal for protecting individual circuits in power distribution systems, industrial controls, and commercial equipment.
