ND63B900L - 900Amp Circuit Breaker

ND63B900L - 900Amp Circuit Breaker

Looking for an ND63B900L circuit breaker for an existing installation? This Type ND6 molded-case breaker is rated at 900 amps and uses a 3-pole configuration. Its interrupting ratings are 25 kA at 600 VAC, 50 kA at 480 VAC, and 65 kA at 240 VAC. It also has an interchangeable trip unit and includes both line- and load-side lugs.

The breaker measures 16 inches high, 9 inches wide, and 6 inches deep, so check the dimensions when matching an existing unit. There's also a 30kAIC at 250VDC rating for applicable 2-pole applications.

For older electrical equipment, finding the right replacement often comes down to the details. Part number, frame type, amperage, poles, dimensions, interrupting rating, and connections must all match the equipment you're working on. When your application calls for these ND6 specifications, the ND63B900L delivers the form and function you need. It's built to last for its intended use without complicating selection.

Where It Works Best

• The ND63B900L makes the most sense when you're repairing or maintaining existing equipment that calls for a Type ND6, 900A, 3-pole molded case circuit breaker with these particular ratings and dimensions.
• Before choosing a replacement, compare it carefully with the existing breaker. Check the part number, ND6 type, amperage, number of poles, voltage, A.I.C. ratings, dimensions, trip-unit configuration, and lug requirements. If those details match your equipment requirements, you've got a much clearer path to finding the right fit.
