Overview

The ABB H250BHD is a 2-1/2 inch zinc bulkhead fitting engineered for secure conduit connections in industrial electrical systems. This fitting features a thermoplastic insulating throat rated at 105°C with a 94V-0 flammability rating, providing reliable protection for conductors against mechanical damage during installation and operation. The included Nitrile (BUNA-N) sealing ring delivers superior resistance to oils, fuels, and chemicals, ensuring a robust seal against environmental contaminants. Designed for compatibility with Rigid and Intermediate Metal Conduit (IMC), the H250BHD establishes watertight and dust-tight connections through bulkheads or enclosures, critical for maintaining electrical system integrity in harsh environments. The zinc-coated hub and locknut offer inherent corrosion resistance, extending service life in challenging industrial atmospheres. This fitting meets NEMA sealing requirements for NEMA 3R, 4, and 13 enclosures, with optional chrome-plated (CP) and 316 stainless steel (GRSST) hubs extending ratings to NEMA 4X and 12. The thermoplastic throat ensures electrical insulation while the BUNA-N seal maintains environmental protection. Key specifications include: 2.5 inch conduit size, zinc hub/locknut material, thermoplastic throat rated to 105°C, and Nitrile (BUNA-N) sealing ring.
