The AA1-B0-26-420-1B1-C is a 1-pole magnetic hydraulic delay circuit breaker from Littelfuse. It is rated for 2A current and 277V voltage, making it suitable for branch circuit protection in AC applications. The breaker features a panel mount design with a lever actuator and is supplied without illumination.
This magnetic hydraulic delay breaker provides precise overcurrent protection. Its hydraulic delay characteristic allows it to handle short inrush currents without nuisance tripping, ideal for motor and lighting circuits. The single-pole construction is common for phase protection.
The breaker is approved by CCC, CSA, and UL, ensuring compliance with major safety standards. It is RoHS3 compliant, REACH unaffected, and has MSL 1 rating (unlimited). These attributes support use in regulated industrial environments.
Typical applications include power distribution panels, HVAC equipment, and machinery control cabinets. The panel-mount form factor simplifies installation in metal enclosures.
