Material Compliance and Certifications

The product specifications provided didn't include certification, listing, or material-compliance information. Don't assume these details based on the ND63B800 part number alone.

If your application requires a particular listing, certification, or compliance standard, check the markings on the individual breaker and the applicable equipment documentation before installation.

Where It Works Best

The ND63B800 makes the most sense when maintaining existing equipment that already calls for an 800A Type ND6 breaker with matching specifications. This may include compatible switchgear, distribution equipment, industrial electrical systems, and other established installations.

For replacement work, start with the existing breaker rather than relying on appearance alone. Match the ND63B800 part number, 800A rating, three poles, voltage and AIC ratings, dimensions, trip configuration, and lug arrangement to the equipment requirements.
