Eaton TMC3-050-1-SS Cable Gland - IP66, NEMA 4X
Part Number: TMC3-050-1-SS
Quick Summary
The Eaton TMC3-050-1-SS cable gland seals armored cables in hazardous locations for industrial automation. Engineers often struggle with reliable ingress protection, rugged mounting, and field-installation compatibility in harsh environments. This gland carries IECEx/ATEX certification, NEC/CEC compliance, and IP66 protection (NEMA 4X), ensuring safety and regulatory alignment across zones. By supporting both armored and non-armored cables and accommodating a wide armor and sheath range, it reduces part count and simplifies procurement. The result is faster installation, predictable maintenance intervals, and lower total cost of ownership in demanding industrial applications.

Eaton Specification Sheet - TMC3-050-1-SS
Stainless steel construction provides corrosion resistance and rugged durability for both armored and non-armored cables, reducing maintenance cycles in washdown and chemical environments. This core design ensures long service life in hazardous locations, where enclosure integrity matters most. Flexible cable and armor range enables a single gland to cover MC, MC-HL, TECK, TC, TC-ER, ITC, ITC-ER, ITC-HL, PLTC, PLTC-ER, and ITC variants. Business impact: minimizes SKU proliferation and accelerates procurement; Application: simplifies field stocking and installation decisions. The 1/2 in NPT threaded entry simplifies integration with standard conduit fittings and panels, reducing installation time and potential leakage points. Armoured and non-armoured compatibility reduces the need for multiple glands and spare parts, ensuring regulatory compliance across diverse cable types. IP66 and NEMA 4X ratings provide ingress protection in wet, dusty, and washdown environments, while IECEx/ATEX and NEC/CEC certifications support global compliance. Installation instructions and data sheets are readily accessible, enabling rapid validation and deployment on site.

FAQs
Installers should prepare the gland with the appropriate sealing components for the cable type, insert the cable through the gland body, and tighten the 1/2 in NPT fitting to the enclosure. For armored cables, ensure the armor is properly engaged with the gland compression to maintain IP66 protection; for non-armored cables, use the standard grommet/retention mechanism. Always follow the IF 1890 installation sheet for sequence and torque guidance to avoid leaks or damage to the seal.
The TMC3-050-1-SS is designed to meet IECEx/ATEX certification along with NEC/CEC compliance, plus IP66 ingress protection and NEMA 4X ratings. These certifications validate suitability for hazardous/classified locations and wet or dusty industrial environments, enabling global deployment in zones requiring rigorous safety and regulatory adherence.
Yes. The gland supports a wide cable range (0.67” to 1.00”) and armour (0.579” to 0.872”), covering MC, MC-HL, TECK, TC, TC-ER, TC-ER-HL, ITC, ITC-ER, ITC-HL, PLTC, PLTC-ER, and ITC variants. Its armoured and non-armoured capability eliminates the need for multiple gland SKUs, simplifying procurement and field installation for automation panels.
The gland’s stainless steel construction and robust sealing reduce maintenance intervals in harsh environments, lowering lifecycle costs. Global certification support (IECEx/ATEX and NEC/CEC) minimizes compliance risk, while universal armoured/non-armoured compatibility reduces spare-part inventory. Overall, you gain faster deployments, fewer part numbers, and predictable performance in hazardous or washdown facilities.
Documentation is readily available: IF 1890 installation sheets, the Crouse-Hinds TMC3 catalog page, and the Eaton specification sheet for TMC3-050-1-SS. These resources provide mounting instructions, torque guidelines, cable compatibility, and certification details to support quick validation and field deployment.
