Eaton Specification Sheet - TMCX300 1 NP
Feature → Business Impact → Application: The Terminator II TMCX300 1 NP employs a metal-clad armoured design with interlocked or welded corrugated armour and a TECK armoured/barrier configuration, delivering superior mechanical protection and sealed integrity. This translates to reduced ingress risk and enhanced protection of sensitive control cables in Hazardous/Classified Locations, ideal for refinery and chemical plant installations. Application: tray cables in explosion-prone zones; benefit: longer service life and lower maintenance costs due to rugged construction. Feature → Business Impact → Application: Nickel-plated brass gland material provides excellent corrosion resistance in wet or chemically aggressive environments, improving uptime and reducing replacement cycles. Application: outdoor or interior hazardous facilities; benefit: extended component life and lower total cost of ownership. Feature → Business Impact → Application: 3" NPT threaded armoured gland with a 1 (S) cable sealing range supports rapid, reliable field assembly and repeatable sealing performance. Application: large-diameter conduit runs; benefit: faster commissioning and easier Glanding in tight spaces. Feature → Business Impact → Application: NEC/CEC compliance and a NEMA 4X enclosure rating mitigate regulatory and safety risks. Application: oil and gas, mining, and chemical plants; benefit: peace of mind, simplified audits, and predictable maintenance cycles. Feature → Business Impact → Application: Cable range of 2.24–3.28 in and armoured barrier configuration ensures compatibility with a wide range of tray cables. Application: end-to-end cabling in hazardous locations; benefit: reduced inventory complexity and single-gland applicability. Feature → Business Impact → Application: Availability of 3D CAD drawings, instruction sheets, and datasheets speeds design validation and on-site installation. Application: engineering design and field service; benefit: shorter project timelines and fewer installation errors.

FAQs
The TMCX300 1 NP uses a 3" NPT thread designed for metal-clad tray cable glands and fits standard enclosure penetrations. It accepts interlocked or welded corrugated armoured cables, with a 1 (S) sealing range for reliable ingress protection. For best results, prepare a clean mounting surface, verify thread engagement, and follow the included IF1647B installation guidelines to ensure compliance in Class I/II environments.
The gland supports cable ranges from 2.24 to 3.28 inches with a 1 (S) sealing range and an armoured sealing configuration suitable for metal-clad and TECK armoured trays. This combination ensures appropriate sealing for larger tray cables while maintaining explosion-protected integrity in hazardous locations.
Yes. The TMCX300 1 NP is rated for NEC hazardous locations including Class I, Division 1, along with Class II Division 1 and Class III. It also carries a NEMA 4X rating, making it appropriate for harsh industrial settings where ignition risks and washdown exposure are present.
This gland complies with NEC/CEC standards, supports hazardous location classifications, and is UL-certified for explosion-proof performance. The NEMA 4X rating adds environmental protection, and UL certifications for the TMCX II family reinforce its suitability for regulated industries like chemical processing, oil and gas, and mining.
The nickel-plated brass construction provides excellent corrosion resistance, reducing replacement frequency in harsh environments. Armour protection minimizes mechanical damage to conductors, lowering downtime. Quick-install 3" NPT threads simplify field assembly, shortening project timelines and delivering a predictable total cost of ownership through improved reliability and fewer maintenance interventions.
