The Cutler Hammer PB31200 is an insulated case circuit breaker engineered to provide reliable overcurrent and short-circuit protection for high-capacity three-phase electrical systems. It features a 1200A continuous current rating and a 600V AC voltage rating, with a robust thermal-magnetic trip unit offering long-time and instantaneous (LI) protection functions. The unit is constructed as a three-pole, bolt-on device with a substantial 175 lb frame, designed for demanding industrial installations. It complies with relevant industry standards for circuit protection and is rated for an interrupting capacity of 100kA at 480V AC. This breaker is typically applied in main service entrances, distribution panels, and large feeder circuits within commercial and industrial facilities.
