The Littelfuse CA1-B2-42-450-121-D is a single-pole magnetic circuit breaker with hydraulic delay, rated for 5A continuous current and 250V AC/DC. It features a lever actuator and is designed for panel mount installation. The hydraulic delay mechanism provides time-delayed overcurrent protection, suitable for handling transient inrush currents without nuisance tripping.
This circuit breaker is qualified under multiple safety standards including CCC, CSA, UL, and VDE, making it suitable for use in a wide range of industrial and commercial equipment. It has a non-illuminated lever actuator, allowing manual reset after a trip event.
The panel mount design enables straightforward installation into control panels, distribution boxes, or equipment enclosures. As a single-pole device, it is intended for single-phase applications or individual branch circuit protection. The hydraulic delay ensures stable operation under varying ambient temperatures.
