The Littelfuse MD2-B-34-620-3-A44-B-C is a 2-pole magnetic circuit breaker designed for reliable overcurrent protection. It features a hydraulic-magnetic delay mechanism, providing precise and stable trip characteristics that are largely unaffected by ambient temperature. This circuit breaker is rated for 20A at 250V and uses a rocker actuator for manual reset and switching.
This component is panel mounted, making it suitable for a variety of industrial and commercial power distribution applications. The hydraulic delay allows for brief current surges without nuisance tripping, ideal for loads with inrush currents. The non-illuminated rocker actuator provides a clear visual indication of the breaker's status.
As a magnetic breaker, it offers fast response to high fault currents while maintaining a time delay for lower-level overloads. This makes it a robust choice for protecting wiring and downstream equipment in control panels, power supplies, and other electrical systems.
