RD63B180 - 1800Amp Circuit Breaker

RD63B180 - 1800Amp Circuit Breaker

When your electrical system calls for a 1800-amp, 3-pole molded case circuit breaker, the RD63B180 delivers the form, fit, and functional compatibility needed to keep compatible power distribution equipment operating as intended. Designed for use with an RD2000A frame and featuring an interchangeable thermal-magnetic trip unit, this breaker helps protect electrical systems against overloads and short circuits while matching the original equipment configuration. Built to last, the RD63B180 is commonly found in commercial and industrial electrical distribution systems where dependable overcurrent protection is essential. Its interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 125kA at 240VAC make it suitable for applications with substantial available fault current. Whether you're replacing an existing breaker during maintenance or restoring equipment to service, this model is designed to provide the compatibility needed for existing installations.
