Overview

The ABB H350A is a 3-1/2 inch aluminum hub connector engineered for secure conduit termination in industrial and commercial electrical installations. Designed for compatibility with Rigid and Intermediate Metal Conduit (IMC), this connector ensures reliable mechanical and electrical connections in demanding environments. The hub connector features a zinc or copper-free aluminum hub and locknut, providing inherent corrosion resistance and durability for long-term performance. Key specifications include a thermoplastic insulating throat rated for 105°C with a 94V-0 flammability rating, protecting conductors from abrasion and damage during installation and operation. The Nitrile (BUNA-N) sealing ring delivers effective resistance to oils, fuels, and certain chemicals, making the H350A suitable for applications where exposure to harsh substances is common. The connector accommodates a maximum panel thickness of 1/4 inch and features a throat diameter of 3 13/32 inches for proper conduit fitment. The H350A is part of ABB’s Installation Products line, a trusted manufacturer in electrical infrastructure solutions. Its robust aluminum construction and precision-engineered design ensure straightforward installation while maintaining safety and longevity in commercial and industrial electrical systems. The 3-1/2 inch trade size is specifically optimized for compatible conduit diameters, providing a secure termination point for Rigid/IMC conduit systems.
