FAQs
Yes. The TMCX300 1 features a 3" NPT thread and is designed for tray cables within the 2.24–3.28 inch range. Its aluminum armor-compatible gland and Armoured seal (1 S) ensure a secure, compliant fit, reducing field rework and enabling faster panel assembly in hazardous locations.
The gland is designed for Hazardous/Classified Locations with NEC/CEC compliance. It carries Class I, Division 1; Class II, Division 1; and Class III hazardous ratings and a NEMA 4X enclosure rating, supporting safe operation in chemical, refinery, and offshore environments.
Yes. The product specifications describe compatibility with TECK armoured, metal-clad, interlocked or continuously welded corrugated armoured, and armoured barrier cables, making it versatile for a range of rugged industrial cabling schemes.
The gland uses a 3" NPT thread and an aluminum body for strength and corrosion resistance. When installing, ensure proper torque on the mating enclosure, verify cable range fit, and confirm gasket seating to maintain the 1 (S) sealing requirement, minimizing leakage risk.
The gland reduces maintenance downtime through reliable sealing and quick installation, lowers rework costs from seal failures, and improves code compliance with NEC/CEC and NEMA 4X protection. Over replacements and corrosion resistance in harsh environments, operators realize lower total cost of ownership.
