The Cutler Hammer PRL2A3600X42C is a 600A, 600V AC panelboard main circuit breaker designed for primary overcurrent protection in industrial power distribution systems. It features a 3-pole, 3-phase configuration with a 65kAIC at 480V interrupting rating, housed in a 60-pound steel enclosure with dimensions suitable for PRL2 series panelboards. The unit utilizes a thermal-magnetic trip mechanism and is UL 489 listed, complying with NEMA and ANSI standards for safe operation in ambient temperatures up to 40°C. This breaker is typically applied in commercial and industrial settings requiring high-amperage main disconnect, such as manufacturing plants, data centers, and large-scale electrical distribution panels.
