Eaton Specification Sheet - TMCXM20 1 NP
Protection type is Explosion-proof, delivering safe operation in hazardous locations and supporting NEC/CEC compliance to minimize regulatory risk in oil, gas, chemical, and mining environments. This translates to fewer unplanned outages and faster commissioning of control panels that rely on armored cable glands. Material is nickel-plated brass, providing excellent corrosion resistance and durability for outdoor or humid facilities, reducing maintenance costs over the gland’s life. Cable range of 12.4-22.8 mm offers flexibility to support multiple cable constructions without swapping glands, saving inventory and installation time in motor starters and control enclosures. Thread size M20 and metric threading enable quick, standardized installation, improving field efficiency and reducing the chance of cross-threading in tight junctions. Barrier type is TSC Compound, ensuring robust isolation and safety within barrier-tested assemblies, which is critical for maintaining integrity in armoured and tray-cable configurations. Certifications, including NEC/CEC and Hazardous/Classified Locations designation with NEMA 4X/6P protection, demonstrate regulatory compliance and reliability for demanding industrial settings. This gland is designed to integrate with metal-clad and interlocked armored cables, TECK armouring, and armoured barriers, simplifying installation and ensuring consistent performance across a broad range of hazardous-location projects. Industry context favors products with standardized features like M20 threads and nickel-brass construction to support long-term uptime, installation compatibility, and reduced maintenance overhead in refinery, chemical processing, and mining facilities.

FAQs
Yes. The TMCXM20 1 NP CableGland is designed for metal-clad with interlocked or welded corrugated armour, TECK armoured, and armoured barrier cable systems. Its M20 thread and nickel-plated brass construction support secure engagement with tray cable and armoured setups, helping maintain seal integrity in harsh environments and simplifying compatibility checks during panel builds.
The gland is certified for Hazardous/Classified Locations under NEC/CEC standards, including NEC Class I Division 1, Class II Division 1, and Class III. It also carries a NEMA 4X 6P rating, indicating strong dust, water, and corrosion resistance, suitable for challenging industrial zones such as refineries, chemical plants, and mining facilities.
Absolutely. The TMCXM20 1 NP features a metric M20 thread size that matches common enclosure glands and panels, enabling straightforward field installation. Ensure correct thread engagement and use appropriate locking methods to maintain the 1 S sealing specification and protect against ingress in hazardous locations.
To ensure reliable sealing, select the gland size that fits the cable diameter within 12.4-22.8 mm, verify the cable construction (metal-clad, corrugated armour), and tighten to the recommended torque, using proper sealing grommets and O-rings if supplied. The 1 S sealing and barrier materials (TSC Compound) are designed to resist moisture and dust, preserving gland integrity under demanding conditions.
The gland contributes to faster installation, reduced maintenance, and lower risk of unplanned downtime in hazardous environments. Its corrosion-resistant nickel-plated brass and explosion-proof design help extend service intervals, while NEC/CEC and NEMA 4X compliance minimize certification hurdles on projects, translating to lower total cost of ownership for oil & gas, chemical processing, and heavy manufacturing facilities.
