Eaton Crouse-Hinds TMC3-100-2 Cable Gland - IP66
Part Number: TMC3-100-2
Quick Summary
The TMC3 cable gland seals armored and non-armored MC cables in hazardous industrial environments. Engineers often grapple with fitting a single gland to a wide range of cable diameters while preserving IP66/NEMA 4X protection under harsh conditions. It carries IECEx/ATEX and NEC/CEC compliance, plus hazardous location ratings, providing confidence in safety, testing, and documentation. Designed for fast installation and broad compatibility, it supports industrial automation wiring and field-bus deployments, delivering reliability, easier procurement, and reduced downtime across modernization projects. This solution works across oil and gas, chemical processing, and water treatment environments, where safety margins and long-term service life matter most.

IF 1890 - TMC3 Cable Gland
Armoured and non-armoured construction in a single TMC3 gland provides installation flexibility across diverse field cables. This reduces inventory costs and simplifies procurement while ensuring a consistent seal in varying cable builds. Application: suitable for MC, MC-HL, TECK, TC, TC-ER, ITC, ITC-ER, ITC-HL, PLTC, PLTC-ER, and ACIC cables in industrial cabinets and outdoor enclosures. 1 in Thread Size and standard 1" NPT thread interface enable direct compatibility with common conduits and enclosures, minimizing adapters and installation time. This translates to faster panel terminations, tighter seals, and fewer potential leak paths in hazardous environments. Armor range 1.100" - 1.400" and cable range 1.150" - 1.620" (outer sheath same) provide broad sizing to accommodate most MC cables used in automation and power feeds. The wide range reduces field modification and returns more predictable sealing performance. IP66 and NEMA 4X protection deliver rugged reliability for washdown and outdoor installations, helping maintenance teams avoid corrosion-related failures and unscheduled downtime. Certifications IECEx/ATEX and NEC/CEC compliance, along with hazardous-location classifications (Class II, Division 1; Class III), support compliance and simplify procurement for regulated facilities. Compatibility with a broad cable catalog and aluminum body keeps weight manageable while offering corrosion resistance, enabling quicker installations and long service life; customers benefit from reduced total cost of ownership and improved field reliability.

FAQs
The TMC3-100-2 gland supports armor ranges from 1.100" to 1.400" and cable ranges from 1.150" to 1.620", for both armored and non-armored MC cables. It is compatible with MC, MC-HL, TECK, TC, TC-ER, TC-ER-HL, ITC, ITC-ER, ITC-HL, PLTC, PLTC-ER, and ACIC cable families, using a 1" NPT inlet in aluminum.
The gland carries IECEx/ATEX and NEC/CEC certifications, with hazardous location ratings including Class II, Division 1 and Class III. It also meets IP66 ingress protection and NEMA 4X, supporting installations in harsh environments and regulated facilities worldwide.
Yes. The TMC3-100-2 is designed for hazardous locations, featuring NEC/CEC and IECEx/ATEX conformity along with hazardous area classifications. It supports Class II, Division 1 and Class III environments, enabling safe use in classification zones typical of chemical plants, refineries, and other critical facilities.
For IP66 installations, ensure a proper 1" NPT connection into the enclosure, verify armor and outer sheath diameters match the gland range (1.100"–1.400" armor and 1.150"–1.620" cable/outer sheath), and use appropriate seals and seals-gaskets. Aluminum construction aids corrosion resistance, while the gland’s sealing ensures reliable performance in washdown and outdoor environments.
By delivering broad cable compatibility, robust IP66/NEMA 4X protection, and IECEx/ATEX/NEC/CEC compliance, the gland reduces downtime, minimizes spare-part inventories, and simplifies regulatory documentation. Its durable aluminum body and straightforward installation contribute to longer service life and lower total cost of ownership across automation and hazardous-location projects.
