The Littelfuse MD1-B-14-630-3-A12-B-T is a single-pole circuit breaker from the MD1-B series, designed for panel mount installation with a rocker actuator. It features a magnetic-hydraulic trip mechanism that provides reliable overcurrent protection with a controlled time delay, making it suitable for applications requiring precise current handling.
This breaker is rated for 30A continuous current and can interrupt circuits up to 250 V AC or 80 V DC. It is approved under CCC and UL489A standards, ensuring compliance with international safety requirements. The non-illuminated rocker actuator offers a simple, user-friendly interface for manual reset.
The panel mount design allows for secure installation in control panels, power distribution units, and industrial equipment. The magnetic-hydraulic delay characteristic helps avoid nuisance tripping from transient inrush currents while still providing fast response to sustained overloads.
