This is an A2A series 2-pole molded case circuit breaker rated 200 A with a 25 kA interrupting capacity. It comes with line lugs and a shunt trip (SB) for remote tripping.
Mounts in a standard panelboard or switchboard enclosure. The 2-pole 200 A frame fits typical commercial and light industrial distribution — think lighting panels, HVAC disconnects, or feeder circuits. The line lugs simplify bus-bar connection; the shunt trip lets a fire alarm or emergency-stop system drop the load remotely.
