Eaton Specification Sheet - TMCX400 1 NP L
Explosion-proof protection with a rugged enclosure provides compliant performance in hazardous locations, reducing ignition risk and inspection overhead for facilities handling volatile materials. Business impact: lower risk, simplified regulatory audits, and longer service intervals in oil, gas, and chemical plants. Application: armoured tray cables feeding critical equipment in refineries. The metal-clad, corrugated armoured TECK armoured configuration delivers enhanced mechanical protection against impact and abrasion; impact: fewer gland-related failures, predictable cable sealing, and reduced downtime during installation, especially in tight spaces on offshore platforms. Application: rugged cable runs between enclosures and junction boxes where vibration and moisture are concerns. Nickel-plated brass material combines corrosion resistance with durability; impact: extended lifecycle in salty or acidic environments, lowering replacement costs. Application: seawater-exposed or chemical-processing facilities that demand longevity and reliability. The Terminator II’s armoured barrier and liquid compound seal provide a reliable seal against dust and moisture ingress while maintaining cable flexibility; impact: consistent electrical performance, easier retrofits, and improved installation speed. Application: retrofit projects or new builds where cable range and seal integrity are critical. 4" NPT thread and armoured gland design enable straightforward mounting and compatibility with standard enclosures; impact: faster commissioning, reduced installation risk, and compatibility with existing mounting footprints. Application: new builds and upgrades in industrial automation systems seeking verified, code-compliant fittings. The cable range of 2.62–3.78" ensures a precise fit for common tray cable sizes, improving sealing effectiveness and eliminating over/under-sizing concerns; impact: optimized material usage, fewer seals, and simplified inventory management. Application: projects with varied cable bundles and tight installation tolerances.

FAQs
For hazardous locations, ensure the gland is mounted on a compatible enclosure with a 4" NPT opening, using the correct sealing range (2.62–3.78 inches) for the tray cable. Verify the environment complies with Class I, Division 1 or equivalent NEC/CEC classifications and confirm UL/NEMA 4X certification coverage. Use proper torque to maintain the liquid compound barrier and ensure the armour remains intact for TECK or metal-clad cables.
The gland uses a liquid barrier and a 1 (S) cable sealing range to seal against dust and moisture while accommodating armoured tray cables. The nickel-plated brass shell provides corrosion resistance, and the 4" NPT thread enables secure mounting. Together, these features maintain a robust IP rating in harsh environments, reducing ingress-related failures and maintenance needs.
Yes. The TMCX400 1 NP L is specified for TECK armoured, metal-clad, interlocked or welded corrugated armour, and armoured barrier configurations. This compatibility supports diverse installation scenarios, from new builds to retrofits, and helps unify fittings across a plant’s cable management system, improving stocking efficiency and field consistency.
The gland is designed for Hazardous/Classified Locations with NEC/CEC standards and Class I, Division 1, Class II, Division 1, and Class III ratings. It carries NEMA 4X protection and UL certification acknowledgments. These certifications support compliance during audits, enabling safer operation in refineries, chemical plants, and mining facilities.
By providing a durable, explosion-proof seal with long-lasting corrosion resistance and a broad cable range, the TMCX400 1 NP L reduces field adjustments, minimizes ingress-related failures, and lowers maintenance frequency. The compatibility with standard enclosures and armour types speeds up installation, shortening project timelines and delivering a favorable total cost of ownership in demanding industrial environments.
