The Square D PowerPact RJF46300CU31A is a premium R-Frame MCCB designed by Schneider Electric for heavy industrial and utility-scale circuit protection. This 4-pole device is rated at 3000A with 600V AC voltage capability and an interrupting capacity of 100kA@240V, 65kA@480V, 25kA@600V (High (J) interrupting class). It features a MicroLogic 3.0 electronic trip unit providing long-time and instantaneous overcurrent protection (LI), rated at 80% continuous current per NEC Article 240.6. The RJF46300CU31A is equipped with busbar connection for direct mounting in power distribution switchgear. This breaker is UL 489 listed and CSA certified with dual UL/IEC ratings, ensuring compliance across North American and international installations. Engineers and contractors rely on the RJF46300CU31A for its proven track record of reliability, ease of installation, and comprehensive protection capabilities. Field-installable accessories include shunt trip coils, undervoltage releases, auxiliary switches, alarm contacts, and motor operators for remote operation. This configuration is suitable for both new installations and retrofit applications in existing switchgear and panelboard assemblies. Maintenance intervals are minimized through the use of high-quality internal components and arc-quenching chamber technology. The wire range accommodates Bus connection (RLTB kit) conductors for flexible installation options. Quick-make quick-break contact mechanisms ensure reliable interruption regardless of handle operating speed or force applied. Physical dimensions of 14.88" H x 15.00" W x 7.00" D with an approximate weight of ~55 lbs ensure compatibility with standard enclosures.
