RD63B200 - 2000Amp Circuit Breaker

RD63B200 - 2000Amp Circuit Breaker

When your electrical system calls for dependable high-current circuit protection, the RD63B200 molded case circuit breaker delivers the ratings and compatibility needed for demanding commercial and industrial applications. Built on the RD2000A frame, this 3-pole, 2000 amp thermal magnetic circuit breaker features an interchangeable trip unit, making it a practical solution for maintaining compatible electrical equipment without changing the existing breaker frame. Its molded case design is built to last, while interrupting ratings of 50kA at 600VAC, 65kA at 480VAC, and 125kA at 240VAC provide the fault interruption capacity required for many high-power distribution systems. Whether you're replacing a compatible breaker during scheduled maintenance or keeping an existing electrical system operating as intended, the RD63B200 is designed to match the original form, fit, and function. Please note that lug terminals are not included, allowing the proper lugs to be selected for your specific installation requirements.
