Overview

ABB CMSU03M-K Flexible Metallic Conduit is a hot-dipped galvanized steel raceway designed for robust electrical wiring protection in industrial and commercial applications. Constructed from helically wound, formed steel strip with a metallic finish, this conduit provides mechanical protection for conductors while allowing flexibility for installation in tight spaces or around obstacles. The 3/4-inch trade size (21mm) accommodates standard wiring configurations and supports long continuous runs with a 150-meter (500-foot) coil length. The conduit meets UL 1 and CSA C22.2 No. 56 standards for flexible metal conduits, ensuring compliance with North American electrical codes. It is suitable for exposed and concealed installations per NEC Article 348, including raceway connections to motors (NEC Section 430.223) and grounding conductor applications (NEC Section 250.118). The hot-dipped galvanized finish provides corrosion resistance, extending service life in demanding environments. Compatible with industry-standard fittings such as T&B Fittings® Ser. XC squeeze/clamp types, Steel City® connectors, and Iberville CI21/CI22/CI40 clamp connectors, this conduit integrates seamlessly with existing electrical systems. Operating temperature range spans -45°C to +400°C (-49°F to +752°F), meeting IEC/EN 61386-1, -23 requirements for global applications. The CMSU03M-K is a non-jacketed, reduced-wall design (Greenfield-style) optimized for electricians and contractors requiring durable, code-compliant conduit for general electrical installations.
