MXD63H800 - 800Amp Motor Circuit Protector

MXD63H800 - 800Amp Motor Circuit Protector

When your motor circuit protector needs replacing, getting the electrical specifications right is only part of the job. The replacement also has to fit the existing equipment, match the required trip characteristics, and work with the motor protection arrangement already in place. For maintenance teams responsible for established electrical systems, those details can determine whether a component is suitable for the application.

The MXD63H800 800 Amp 3-Pole Motor Circuit Protector is a Type MXD6 magnetic-only circuit protection device rated at 800 amps and 600VAC. Designed for motor circuit applications requiring instantaneous magnetic tripping, it has a specified trip adjustment range of 5,000 to 10,000 amps. This makes the MXD63H800 a component to consider when maintaining equipment that calls for this particular combination of amperage, pole configuration, voltage rating, and magnetic trip characteristics.

Material Compliance and Certifications

The supplied information does not identify the housing material, internal contact materials, terminal construction, or mounting hardware. It also does not independently confirm a UL listing, CSA certification, or other product-specific approval. These details should be checked against the manufacturer's documentation and the markings on the actual equipment.

The complete motor circuit installation must meet applicable National Electrical Code (NEC) requirements, local electrical regulations, and the manufacturer's instructions. In particular, motor branch-circuit short-circuit and ground-fault protection should be evaluated in conjunction with the required motor overload protection.
