Eaton TMCXM20 1 NP L Cable Gland - Explosion-Proof 4X
Part Number: TMCXM20 1 NP L
Quick Summary
TMCXM20 1 NP L is an explosion-proof cable gland for terminating TECK armoured cables in hazardous locations. End users often struggle with reliable sealing and regulatory compliance in harsh settings; this gland delivers robust protection and proven sealing performance. It meets NEC/CEC standards, UL certification, and NEMA 4X/6P ratings for Hazardous/Classified locations. This model's M20 thread and nickel-plated brass construction simplify installation and support TECK armoured, liquid-compound barrier, and tray cable configurations. In engineering terms, the TMCXM20 1 NP L reduces inventory complexity by offering a single sealing range and a single gland type suitable for multiple cable types. That's particularly valuable in hazardous-location projects where downtime costs and compliance gaps impact project budgets.

Eaton Specification Sheet - TMCXM20 1 NP L
Explosion-proof design minimizes ignition risk by containing sparks or fumes within the gland and enclosure, improving site safety and lowering insurance and downtime costs in oil & gas, petrochemical, and mining facilities. This translates to faster commissioning and fewer regulatory hold-ups during plant turnarounds, while maintaining NEC/CEC compliance and UL listings for critical equipment. The M20 metric thread and nickel-plated brass body deliver robust mechanical durability and corrosion resistance, enabling reliable performance in humid or chemically aggressive environments and simplifying supplier qualification for panel builders and integrators. Cable range compatibility of 12.4-22.8 mm with a single sealing option (1 S) reduces spare part variety, streamlining procurement and stocking for maintenance teams. TECK armoured, metal-clad, barrier, and tray cable configurations are supported, providing installation flexibility across motor starters, control panels, and junction enclosures in harsh locations. This gland also accommodates interlocked or welded armour types, improving long-term stability in vibration-prone installations and minimizing reworks.

FAQs
For field installs in Class I, Division 1 environments, ensure enclosure integrity is intact and the gland is torqued to spec to maintain the 1 (S) sealing rating. Verify cable range compatibility (12.4-22.8 mm) and confirm TECK armoured or metal-clad cables are correctly terminated with the armoured gland. Use compatible anti-seize compounds only where recommended and follow UL/certification guidelines during panel assembly.
Key specifications include M20 thread size on a nickel-plated brass body, cable sealing range 12.4-22.8 mm with a single sealing option (1 S), and armoured gland type designed for TECK armoured, metal-clad, barrier, and tray cable. This gland is explosion-proof with NEC/CEC compliance, UL-listed, and rated for Hazardous/Classified Locations with NEMA 4X 6P protection.
Yes. The gland is specified for TECK armoured and other armoured cable types, including metal-clad with interlocked or welded corrugated armour. It supports armoured barrier and tray cable configurations, providing reliable sealing and mechanical protection while maintaining electrical integrity in harsh environments.
The TMCXM20 1 NP L carries NEC/CEC standard compliance, UL certification, and a NEMA 4X 6P rating for hazardous locations. Area classification is Hazardous/Classified Locations, ensuring safe operation in Class I, Division 1 environments and similar regulatory contexts. These certifications support safe installation and facilitate audit-ready documentation.
By consolidating sealing into a single 12.4-22.8 mm range and using a durable nickel-plated brass body, maintenance intervals are extended and spare-part kits reduced. The explosion-proof design lowers risk of unplanned downtime, improving overall equipment reliability and uptime in hazardous facilities. Compatibility with TECK armoured and tray cables also reduces replacement cycles when cabling configurations change.
