ND63B100 - 1000Amp Circuit Breaker

ND63B100 - 1000Amp Circuit Breaker

The ND63B100 is a Type ND6, 3-pole, 1000A molded-case circuit breaker intended for use in compatible existing electrical equipment. If you're replacing an ND6 breaker, the important thing is getting the specifications right—not just the amp rating. This model measures 16" high x 9" wide x 6" deep, uses an interchangeable trip unit, and includes load-side lugs.

Its interrupting ratings are 25kAIC at 600VAC, 50kAIC at 480VAC, and 65kAIC at 240VAC. It also carries a 30kAIC rating at 250VDC for applicable 2-pole applications.

For maintenance teams, electricians, and facilities working with existing ND6 equipment, the ND63B100 provides clear specifications to match the breaker being replaced. These breakers were built to last, which is one reason they still appear in established electrical systems. As with any replacement breaker, confirm the complete electrical and physical requirements before installation.

Material Compliance and Certifications

• The supplied specifications for the ND63B100 did not include specific agency certifications, listing numbers, or material compliance information, so do not assume them.
• If the application requires a particular certification or listing, check the breaker markings and supporting documentation before installation.
  

Where It Works Best

• The ND63B100 is primarily a replacement option for existing electrical equipment that calls for a Type ND6, 3-pole, 1000A molded case circuit breaker with matching specifications.
• When replacing an existing breaker, don't match on amperage alone. Check the breaker type, number of poles, voltage, AIC rating, physical dimensions, trip-unit configuration, lug arrangement, and equipment compatibility. Small differences matter when you're trying to maintain the correct form, fit, and function.
