JXD63L400 - 400Amp Motor Circuit Protector

JXD63L400 - 400Amp Motor Circuit Protector

A key identifier on the JXD63L400 is its 1,250A to 2,500A instantaneous trip range. Pair that with its 400A rating, three-pole configuration, 600VAC specification, and JXD6(A) type, and you have the main electrical details needed to check compatibility with an existing motor circuit. The JXD63L400 is built to last, with the emphasis for replacement work remaining on correct form, fit, and function. When working with legacy equipment, confirm the complete electrical and physical specification rather than relying on the 400A rating or part number alone.

Key Features and Benefits

• 400A current rating for systems specifically requiring this amperage.
• Three-pole configuration provides an important compatibility reference for three-pole motor circuits.
• Classified as a Motor Circuit Protector (MCP).
• Uses a magnetic-trip-only configuration.
• The 600 VAC specification helps identify the required electrical configuration.
• Well suited to form, fit, and functional replacement where the existing system calls for these exact specifications.

Material Compliance and Certifications

Specific material compliance and certification information was not included in the supplied specifications for the JXD63L400. UL, CSA, IEC, RoHS, REACH, or other certification status should therefore not be assumed. If a particular approval or compliance standard is required for the installation, confirm it using the applicable product documentation.

Where It Works Best

The JXD63L400 motor circuit protector is suited to compatible existing and legacy motor-circuit equipment requiring a 400A, three-pole, Type JXD6(A) device with magnetic-only tripping at 600VAC. Its 1,250A to 2,500A instantaneous-trip range is an especially important specification when determining whether it meets the existing system's protection requirements.
