Allen-Bradley 105-PW55 Circuit Breaker is a thermal-magnetic molded case circuit breaker designed for primary overcurrent and short-circuit protection in industrial power distribution systems. It is rated for 600V AC maximum and carries a continuous current rating of 55A, with a 65kAIC at 240V AC for high-fault applications. The unit features a compact 3-pole configuration with a 1.5-inch per pole frame, constructed from durable thermoset resin and copper alloy conductors, weighing 1 lb. It complies with UL 489 and CSA C22.2 No. 5 standards for branch circuit protection. Typical applications include motor control centers, panelboards, and industrial machinery requiring reliable overload and short-circuit interruption.
