The AJ1-B0-12-620-1B1-C is a single-pole magnetic-hydraulic circuit breaker from Littelfuse. It is rated for 20A at 277V and uses a rocker actuator. The breaker has no illumination and is designed for panel mounting.
Magnetic-hydraulic breakers use a hydraulic delay mechanism to provide time-delayed overcurrent protection. The 20A current rating and 277V voltage rating define the operating envelope for this single-pole device.
The panel mount configuration supports installation in equipment enclosures and control panels. The rocker actuator provides a manual switching interface, and the non-illuminated design keeps the actuator simple. As a single-pole breaker, it protects one conductor in the circuit.
