ND63B100L - 1000Amp Circuit Breaker

ND63B100L - 1000Amp Circuit Breaker

Need an ND63B100L circuit breaker for a compatible existing electrical system? This 1000A, 3-pole Type ND6 molded case circuit breaker is designed for applications where matching the correct breaker specifications, physical footprint, and electrical ratings matters. The ND63B100L features an interchangeable trip unit and comes with line- and load-side lugs, making it well-suited for maintaining compatible electrical distribution equipment. Its interrupting ratings include 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC, plus 30kAIC at 250VDC for 2-pole applications. Measuring approximately 16 inches high, 9 inches wide, and 6 inches deep, this breaker can be a practical form, fit, and functional replacement when those dimensions and ratings match the existing installation. Simply put, when you're working with legacy equipment, getting the details right matters, and the ND63B100L provides clear specifications to help you confirm compatibility. It's a straightforward, built-to-last solution for applications that call for this specific ND6 breaker configuration.

Material Compliance and Certifications

• The available specifications for the ND63B100L did not include material-compliance information or specific agency certifications. Rather than assume certifications or listings, verify these requirements through product markings or applicable technical documentation. If your installation requires a specific listing, certification, material standard, or code requirement, confirm the breaker meets those requirements before installation.
  

Where It Works Best

• The ND63B100L 1000A molded case circuit breaker is best suited to compatible existing and legacy electrical distribution systems that require the Type ND6 configuration. It's particularly useful when you're trying to match an existing installation and need the right combination of 1000A capacity, 3 poles, physical dimensions, trip-unit arrangement, and interrupting ratings.
• For AC applications, match the required system voltage and available fault current against the breaker's stated ratings of 25kA at 600VAC, 50kA at 480VAC, or 65kA at 240VAC. For applicable DC installations, the specified rating is 30 kAIC at 250 VDC for 2-pole applications. The breaker's 16 x 9 x 6-inch dimensions are also worth checking carefully when fit within existing equipment is a key consideration.
• When you're maintaining older electrical equipment, don't complicate the description; the right breaker is the one whose form, fit, ratings, and functionality match the application. Verify those details, including voltage, amperage, interrupting capacity, trip requirements, conductor requirements, and physical compatibility, before installation.
