The Littelfuse AA1-B0-12-630-4C1-C is a single-pole magnetic circuit breaker featuring a hydraulic delay mechanism. It is rated for 30A of continuous current at 277V AC, making it suitable for branch circuit protection in commercial and industrial power distribution systems.
The breaker uses a magnetic (hydraulic delay) trip characteristic, which provides precise overcurrent protection while allowing for temporary inrush currents without nuisance tripping. The lever actuator offers clear visual indication of the breaker state and allows for manual reset.
This component is designed for panel mount installation and carries approvals from CCC, CSA, and UL, indicating compliance with major international safety standards. The non-illuminated actuator keeps the design simple and reliable for demanding environments.
