NXD63B100L - 1000Amp Circuit Breaker

NXD63B100L - 1000Amp Circuit Breaker

When you're replacing a breaker in an existing electrical system, getting the details right matters. The NXD63B100L is an NXD6 molded-case circuit breaker rated at 1000 amps with a 3-pole configuration. It has a non-interchangeable trip unit and includes both line and load-side lugs. For AC applications, its interrupting ratings are 25 kA at 600 VAC, 50 kA at 480 VAC, and 65 kA at 240 VAC. It also has a 30 kA rating at 250 VDC for applicable 2-pole applications. The breaker measures approximately 16 inches high, 9 inches wide, and 6 inches deep. Check those dimensions when working with older equipment, where available space and mounting requirements can matter as much as the electrical ratings. Built to last, the NXD63B100L is intended for compatible systems that call for this particular NXD6 configuration. Before using it as a replacement, check the existing breaker and equipment requirements carefully, not just the amperage, but also the voltage, A.I.C. rating, poles, trip configuration, dimensions, and connections.

Key Features and Benefits

• 1000A, 3-pole configuration for compatible electrical distribution applications.
• NXD6 molded case design for equipment that requires this specific breaker type.
• Rated 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC.
• 30kA at 250VDC rating for applicable 2-pole applications.
• Non-interchangeable trip unit provides the specified trip configuration for this model.
• Line and load-side lugs are included with the breaker.
• Measures 16 x 9 x 6 inches, making it easier to compare the physical footprint with the existing installation.

Material Compliance and Certifications

• The available specifications for the NXD63B100L do not include specific material compliance information or certification listings. If your application requires a particular UL, CSA, RoHS, REACH, or other certification or compliance standard, verify that information from the breaker nameplate or applicable technical documentation before installation.

Where It Works Best

• The NXD63B100L is best suited for compatible legacy electrical equipment that requires an NXD6 1000A molded case circuit breaker with the same physical and electrical characteristics. It may be used in compatible industrial, manufacturing, commercial, and facility electrical distribution applications.
• For replacement work, start with the existing equipment requirements. A matching amperage rating by itself doesn't confirm compatibility. Check the part number, breaker type, number of poles, voltage, interrupting rating, trip configuration, dimensions, and lug arrangement. When those details match the equipment requirements, the NXD63B100L provides the intended form, fit, and function for the application.
