Abb TCU35 Universal Raintight Hub 3.5 Inches Large Base

Product Description

The ABB TCU35 is a large-base universal raintight hub designed for use with ABB load centers and panels in outdoor enclosure applications. With a hub diameter of 3.5 inches and a base size of 4 inches, this fitting provides a weathertight conduit entry point rated for raintight service. Licensed electricians install this hub to protect conduit entries on outdoor electrical enclosures from moisture intrusion, helping maintain the integrity of the installation in exposed or wet-location environments.

The TCU35 is intended for use on 40-circuit and 42-circuit ABB load center units installed in R8 boxes only. This makes it a purpose-matched component for specific panel configurations where a large-base hub entry is required. It is well suited for residential and light commercial electrical installations where outdoor panels require raintight conduit connections.
