Overview

The ABB CMSUS04M-B Flexible Metallic Conduit is a hot-dipped galvanized steel raceway designed for robust wire and cable protection in electrical installations. Constructed from helically wound, formed steel strip with a metallic finish, this conduit provides durable mechanical protection while maintaining flexibility for routing in exposed or concealed locations. The 1-inch nominal trade size (27mm) accommodates multiple conductors, making it suitable for moderate to large-scale wiring projects. Supplied in a 15-meter (50-foot) length, the CMSUS04M-B is optimized for installations requiring extended runs without excessive splicing. The conduit meets UL 1 and IEC/EN 61386-1 standards, ensuring compliance with North American and international electrical codes. It is compatible with industry-standard fittings, including T&B Fittings®, Steel City®, and Iberville clamp-type connectors, facilitating seamless integration into existing systems. The hot-dipped galvanized finish provides corrosion resistance, extending service life in demanding environments. With a working temperature range of -45°C to +400°C (-49°F to +752°F), this conduit is suitable for applications where thermal stability is critical. Ideal for use as a metal raceway per NEC Article 348, it serves as an equipment grounding conductor (Section 250.118) and is permitted for raceway connections to motors (Section 430.223). The CMSUS04M-B is a versatile solution for industrial, commercial, and institutional wiring systems requiring reliable, code-compliant conduit protection.
