The Littelfuse AA1-B0-34-615-7G1-C is a single-pole magnetic (hydraulic delay) circuit breaker designed for overcurrent protection. It is rated for 15A continuous current at 277V, making it suitable for a variety of AC and DC applications. The hydraulic delay mechanism provides time-delayed tripping, allowing for nuisance-free operation during temporary inrush currents.
The breaker features a lever actuator for manual on/off control and is designed for panel mount installation. It is a non-illuminated, compact unit that integrates into standard cutouts. The magnetic trip element ensures fast response to high fault currents, while the hydraulic delay provides coordination with downstream loads.
This circuit breaker is commonly used in industrial control panels, power distribution, and equipment requiring reliable overcurrent protection. Its panel mount design simplifies installation in enclosures and cabinets. The AA1 series offers a robust construction for demanding environments.
