The Littelfuse AA1-B0-12-630-E92-D is a single-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection in electrical systems. It is rated for a continuous current of 30A at 277V AC, making it suitable for branch circuit protection in commercial and industrial applications.
The breaker uses a magnetic-hydraulic trip mechanism that provides precise, temperature-stable overcurrent protection. The hydraulic delay allows for momentary inrush currents without nuisance tripping, while still providing fast response to high fault currents. The lever actuator offers clear visual indication of the breaker state and allows for manual reset.
This circuit breaker is panel mounted, making it suitable for integration into control panels, distribution boards, and equipment enclosures. It carries approvals from CCC, CSA, UL, and VDE, indicating compliance with major international safety standards.
