Overview

The ABB H250A is a 2-1/2 inch aluminum hub connector designed for use with rigid and intermediate metal conduit (IMC). This connector features a thermoplastic insulating throat, providing essential protection for conductors against abrasion and damage during installation and operation. The integrated sealing ring is constructed from Nitrile (BUNA-N), a material known for its resistance to oils, fuels, and certain chemicals, ensuring a reliable seal against environmental ingress. Manufactured by ABB - Installation Products, this hub connector (SKU: H250A) is built to facilitate secure and compliant conduit terminations in various industrial settings. Its aluminum construction offers good corrosion resistance, suitable for environments where moisture or mild chemical exposure is a concern. The 2-1/2 inch size is specified for compatibility with corresponding conduit diameters. The insulating throat is a critical safety feature, preventing damage to wire insulation and ensuring electrical integrity. The BUNA-N sealing ring contributes to maintaining the integrity of the enclosure or junction point, preventing the passage of dust, moisture, and other contaminants. This component is essential for creating safe and durable electrical pathways in industrial facilities, commercial buildings, and other applications requiring robust conduit systems.
