The Littelfuse BB2-B0-44-450-121-D is a 2-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection. It is rated for 5A continuous current at 250V AC/DC. The breaker uses a magnetic hydraulic delay mechanism, which provides a time-delay response to transient currents while offering fast trip on high fault currents. It is approved by CCC, CSA, UL, and VDE, indicating compliance with international safety standards. The circuit breaker is panel mounted with a lever actuator for manual reset and on/off control. It is non-illuminated and comes in a standard 2-pole configuration suitable for branch circuit protection in industrial, commercial, and residential applications. Typical applications include power distribution, motor protection, and general-purpose circuit isolation. The hydraulic delay characteristic makes it ideal for loads with inrush currents, such as motors and transformers. The panel mount design allows for easy installation in control panels and switchgear.
