This is a 1-pole magnetic (hydraulic delay) circuit breaker from Littelfuse, part of the AA1 series. It is rated for 4A continuous current at 277V AC. The breaker uses a hydraulic-magnetic trip mechanism, providing precise overcurrent protection with time delay characteristics.
The breaker features a lever actuator for manual on/off control and is designed for panel mount installation. It has no illumination. The single-pole configuration makes it suitable for protecting individual branch circuits.
With a current rating of 4A and voltage rating of 277V, this breaker is commonly used in lighting control, HVAC, and industrial equipment applications where reliable overcurrent protection is required. The hydraulic delay allows for handling inrush currents without nuisance tripping.
