The Littelfuse AA1-B0-42-615-1B1-C is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in panel mount applications. It is rated for 15A continuous current at 277V AC, making it suitable for commercial and industrial circuits.
The breaker employs a magnetic hydraulic delay mechanism, which provides time-delay tripping to tolerate transient inrush currents without nuisance trips. The lever actuator allows manual on/off control and trip indication. The non-illuminated design simplifies installation in standard panel cutouts.
Panel mount configuration with screw terminals enables secure wiring in control panels, distribution boards, and equipment enclosures. The single-pole format is ideal for branch circuit protection in single-phase systems.
