Sylvania QFB24-3NA Molded Case Circuit Breaker

SYLVANIA QFB24-3NA Molded Case Circuit Breaker is a three-pole (3P) device rated for 225 amperes, designed to provide overcurrent protection for three-phase circuits in electrical distribution systems. As a molded-case breaker, it uses a thermal-magnetic trip mechanism to respond to overloads and short circuits, enabling fast, safe disconnection of a faulted circuit. The QFB24-3NA is intended for commercial and industrial panel installations where robust protection of feeders and branch circuits is required, and it offers the rugged, compact form factor typical of MCCBs used in distribution gear. With a 225 A rating, it is suited to medium- to large-capacity load centers that need a single device to protect substantial current while maintaining coordination with upstream protection. For precise specifications such as operating voltage, interrupting capacity, mounting method, and panel compatibility, refer to the official Sylvania catalog or consult a qualified distributor to verify fit and ensure safe operation.
