Overview

The ABB H400CAP 4-inch zinc capoff is a rugged termination accessory designed for Rigid and Intermediate Metal Conduit (IMC) systems. Constructed from durable zinc with a thermoplastic insulating throat, this capoff provides electrical insulation and environmental protection at conduit terminations. The included Nitrile (BUNA-N) sealing ring ensures a tight, moisture-resistant seal to prevent water ingress, dust contamination, and corrosion in industrial and commercial installations. Key specifications include a 4-inch trade size, zinc construction for corrosion resistance, and a thermoplastic insulating throat rated for electrical safety. The Nitrile sealing ring offers temperature resistance from -40°F to 250°F (-40°C to 121°C), making it suitable for outdoor and harsh indoor environments. The H400CAP is UL-listed and designed for use with Rigid and IMC conduit, ensuring compliance with NEC and industry standards. Applications include industrial facilities, commercial buildings, power distribution systems, and infrastructure projects where conduit terminations require reliable sealing and insulation. The zinc construction provides long-term durability, while the thermoplastic throat prevents electrical contact with conduit ends. The Nitrile sealing ring maintains integrity under vibration and thermal cycling, reducing maintenance needs in dynamic environments. Compatible with standard 4-inch Rigid and IMC conduits, the H400CAP simplifies termination workflows by eliminating the need for additional sealing compounds or tape. Its design allows for quick installation with common tools, reducing labor time and costs. The product is part of ABB’s Installation Products line, known for reliable electrical infrastructure solutions.
