The Littelfuse AA1-B0-26-620-2B1-C is a panel-mount, single-pole circuit breaker utilizing a magnetic (hydraulic delay) trip mechanism. It is rated for 20A continuous current at 277V AC/DC, making it suitable for branch circuit protection in industrial control panels, HVAC equipment, and power distribution units.
This breaker features a lever actuator for manual on/off control and requires no external illumination. Its hydraulic delay mechanism provides inverse time-current characteristics, allowing brief inrush currents without nuisance tripping while protecting against sustained overloads and short circuits.
The AA1-B0-26-620-2B1-C carries approvals from CCC, CSA, and UL, ensuring compliance with international safety standards. The panel mount design simplifies installation in enclosures or equipment chassis.
