MXD63H800 - 800Amp Motor Circuit Protector Description

MXD63H800 - 800Amp Motor Circuit Protector

The MXD63H800 is an 800-amp, 3-pole motor circuit protector from the MXD6 series. It's designed for motor circuits that need instantaneous magnetic protection against high-current faults. This model is rated for 600VAC and has an adjustable trip range of 5,000 to 10,000 amps. Since it uses a magnetic-only trip mechanism, it doesn't provide thermal overload protection. A separate device in the motor control system must handle that function. If you're replacing an existing MXD63H800, matching the original specifications is important. The unit measures 16 inches tall, match wide, and 6 inches deep, soto check the available space and mounting arrangement before installation. It's built to last in industrial applications where the correct electrical components are essential to keeping equipment operating as intended. For maintenance work involving older motor control centers, industrial panels, or machinery that uses this particular MXD6 model, the MXD63H800 provides the same specified ratings and trip characteristics needed for a matching replacement.

Key Features and Benefits

  • For motor circuits requiring an 800A protective device.
  • Designed for compatible three-phase motor systems.
  • 600VAC rating suitable for installations within the specified voltage rating.
  • The magnetic trip trips only in response to high-current faults. Motor overload protection must be provided separately where required.
  • 5,000A–10,000A trip range, with adjustable instantaneous trip settings to meet the motor circuit's protection requirements.
  • MXD6 series intended for equipment that uses this specific motor circuit protector.
  • Made for industrial electrical applications where durable components are needed.
  • Measures 16 inches high, 9 inches wide, and 6 inches deep.

Material Compliance and Certifications

  • Specific information on the MXD63H800's construction materials and certifications has not been provided. UL, CSA, and other applicable approvals should be checked against the product label or manufacturer documentation.
  • The unit is rated for 800 amps and 600VAC and uses a magnetic-only trip mechanism. Confirm its numerical interrupting capacity (AIC) before installation, as this information is not included in the available specifications.
  • Follow applicable electrical codes and the requirements of the existing equipment during installation. Because this protector doesn't include thermal overload protection, you may need a separate overload device.

Where It Works Best

  • The MXD63H800 motor circuit protector is primarily used in existing industrial motor control systems that require this particular MXD6 model. It's a good replacement option when the original protector must match the part number, electrical ratings, and physical configuration.
  • Common applications include:
    • Motor Control Centers: For replacing matching motor circuit protectors in compatible MCC assemblies.
    • Industrial Machinery: Used in motor circuits for manufacturing and production equipment.
    • Pump and Conveyor Systems: Suitable for compatible motor control installations with the required protection arrangement.
    • Industrial Electrical Panels: For existing equipment designed to accommodate this MXD6 model.
    • Legacy Motor Control Systems: Useful when maintaining the original electrical setup without changing the specified protection components.
