The AA1-B2-34-615-5B1-C is a magnetic circuit breaker from Littelfuse Inc. with a hydraulic delay mechanism. It is rated for 15A continuous current and 277V AC voltage, making it suitable for branch circuit protection in industrial and commercial applications. The single-pole design provides overcurrent protection for one phase, and the hydraulic delay allows for precise time-current characteristics to handle inrush currents without nuisance tripping.
This circuit breaker features a panel mount configuration with a lever actuator for manual reset and on/off control. The lever actuator provides clear visual indication of the breaker state. The non-illuminated design is common for standard circuit protection tasks where visual status is not required.
The magnetic trip mechanism ensures fast response to short circuits, while the hydraulic delay provides tolerance for temporary overloads. This combination is ideal for motor circuits, lighting systems, and other inductive loads. The panel mount style allows for easy installation in control panels and enclosures.
The operating voltage is 277V AC.
The current rating is 15A.
It has 1 pole.
It uses a magnetic (hydraulic delay) mechanism.
It is panel mount.
It has a lever actuator.
