KCDP-4C  - 400 Amp Max. Rated Mounting Kit

If you're replacing missing or worn-out hardware on a 400-amp breaker setup, the KCDP-4C mounting kit is exactly what you need. It’s a well-built aftermarket solution made to take the place of the original mounting hardware—no modifications, no guesswork.

This is the kind of part you install once and forget about. It fits right, holds firm, and does the job without getting in the way. Whether you're working in a commercial building or on an industrial panel, it’s a straightforward fix that keeps things moving.
