Overview

ABB Installation Products CMACS03M-L is a heavy-gauge flexible metallic conduit constructed from aluminum alloy, designed for robust electrical wiring protection in industrial and commercial applications. The 3/4-inch trade size (21mm) provides a balance of mechanical strength and installation flexibility, suitable for conduit runs requiring durability without excessive rigidity. Each reel delivers 300 meters (1,000 feet) of conduit, significantly reducing splicing requirements and installation time compared to shorter lengths. The metallic construction offers superior impact resistance, crush protection, and abrasion resistance compared to non-metallic alternatives, making it ideal for harsh environments where conductor integrity is critical. The aluminum alloy material provides inherent corrosion resistance while maintaining a lightweight profile for easier handling during installation. Unlike rigid conduit systems, the flexible design accommodates vibration, thermal expansion, and structural movement without compromising conductor protection. This makes CMACS03M-L particularly effective in applications subject to dynamic forces or where conduit routing must navigate obstacles. Common installations include industrial machinery wiring, commercial building electrical systems, renewable energy installations, and manufacturing facilities. The conduit's metallic construction also provides electromagnetic shielding for sensitive circuits, reducing interference in control and instrumentation applications. The 3/4-inch size is widely compatible with standard fittings and connectors, ensuring straightforward integration into existing systems. Available in standard reel packaging for bulk distribution, CMACS03M-L is specified where long continuous runs are required without intermediate joints. The product's construction and materials are optimized for North American electrical code compliance through UL and CSA certifications.
