MXD63A800 - 800Amp Motor Circuit Protector

MXD63A800 - 800Amp Motor Circuit Protector

The MXD63A800 is a three-pole, 800-amp circuit breaker from the MXD6 series, designed for electrical systems with magnetic-only trip protection. It has a 600VAC voltage rating and an instantaneous trip range of 4,000 to 8,000 amps. This model has no thermal trip function, so check what your existing equipment calls for before using it as a replacement.

Working with older electrical equipment often means finding parts that match the original setup. That's where the MXD63A800 comes in. At 16 inches high, 9 inches wide, and 6 inches deep, it has specific dimensions that need to be considered along with its electrical ratings. The breaker is built for long-term use in compatible installations, whether it's part of an industrial electrical system or commercial power distribution equipment. If you're replacing the same model, check the mounting arrangement, terminal connections, and trip requirements to confirm it's the right fit. Two breakers can have the same amperage and still be designed for different applications.
