Product Description

The SQUARE D H050CP is a plate type hub accessory designed for use with heavy-duty safety switches installed in NEMA 4, 4X, 5, and 12 rated enclosures. This hub provides a secure conduit entry point at the enclosure knockout, maintaining the environmental integrity of the enclosure while allowing conductors to pass through cleanly. It is a compact component measuring 1.8 inches in length, 1.4 inches in width, and 1.4 inches in height, and weighs 0.3 pounds. Electricians and maintenance technicians working on industrial or commercial disconnect installations rely on accessories like this to preserve enclosure ratings after field wiring.
