RJF36200CU44AYP

The RJF36200CU44AYP is a Square D PowerPacT R-frame molded case circuit breaker rated for 2000 amps at 600V with 3 poles, designed to protect large feeders, mains, and switchboard circuits from overloads, short circuits, and ground faults in industrial and commercial power distribution. With an interrupting rating of 65kA@480V, it can safely interrupt the very high fault currents found on large systems. It is rated for 100 percent continuous current, so it can carry its full 2000 amp rating without derating. The RJF36200CU44AYP has a Micrologic 6.0A electronic trip unit with long-time, short-time, instantaneous, and ground fault (LSIG) protection. The adjustable settings let engineers coordinate the breaker with upstream and downstream devices, and the ammeter display shows the load current at a glance. PowerPacT R-frame breakers are dual rated to UL 489 and IEC 60947-2, use dual-break contacts, and have an integral push-to-trip button in the cover that lets the breaker be tripped manually for testing. Mechanically, the RJF36200CU44AYP is a unit mount breaker with a busbar connection, an operating handle, and HACR rating. It measures about 16.24 inches high, 16.53 inches wide, and 14.49 inches deep, and it is built to bolt into switchboards and large enclosures. PowerPacT R breakers comply with UL, CSA, NOM, and IEC standards and are CE marked. Because Square D builds this breaker with different trip units, interrupting ratings, and accessories, it is worth confirming the full part number, including the suffix, against your equipment before ordering. This makes the RJF36200CU44AYP a practical choice for engineers and maintenance teams who need to replace or specify a main or feeder breaker in a large switchboard.
