The Littelfuse AA1-B0-32-475-1D7-C is a single-pole magnetic circuit breaker featuring hydraulic delay for reliable overcurrent protection. It is rated for 7.5A continuous current at 277V AC/DC, making it suitable for branch circuit protection in industrial and commercial equipment.
The breaker uses a magnetic (hydraulic delay) trip mechanism, which provides precise current sensing and time-delayed tripping to avoid nuisance trips from transient inrush currents. The lever actuator allows for manual on/off control and visible trip indication.
This circuit breaker is designed for panel mount installation with a snap-in mounting style, simplifying assembly into enclosures and control panels. It carries approvals from CCC, CSA, and UL, indicating compliance with international safety standards.
