Eaton Specification Sheet - TMC3-050-1
Armor range and cable compatibility deliver a precise seal: armor 0.579 to 0.872 inches and cable range 0.67 to 1.00 inches ensure a secure fit that minimizes moisture ingress and abrasion wear. Business impact: reduced maintenance cycles and lower replacement costs in exposed locations. Application: suitable for armored and non-armored MC cables in outdoor enclosures and wet plant areas. The 1/2 inch NPT thread provides straightforward installation with standard conduit fittings. Business impact: faster field assembly and fewer sourcing delays. Application: enables rapid upgrades in control panels and machine housings without special adapters. IP66 and NEMA 4X protection offer robust dust, water, and corrosion resistance. Business impact: enhanced reliability and regulatory compliance in hazardous locations. Application: ideal for mining, oil & gas, and industrial automation enclosures. Aluminum body keeps weight manageable and corrosion resistance high. Business impact: easier handling during maintenance and reduced logistics costs. Application: scalable across multiple line setups with consistent performance. Documentation and installation resources improve onboarding and reduce commissioning time. Business impact: lower lifecycle costs and faster time to first production. Application: rely on IF 1890 instruction sheets and Eaton data sheets for best practices.

FAQs
For armored and non-armored MC cables, select the gland that accommodates armor between 0.579 and 0.872 inches and cables from 0.67 to 1.00 inches. Use a 1/2 in NPT entry with appropriate thread sealant and matching conduit fittings. Ensure the aluminum gland is properly seated to maintain IP66 integrity and verify compatibility with the enclosure’s internal clearance to avoid exerting pressure on conductors.
The TMC3-050-1 offers IP66 protection and NEMA 4X enclosure protection, along with NEC/CEC IECEx/ATEX certifications for hazardous and classified locations. It is suitable for Class II, Division 1 and Class III environments, supporting safe operation in industrial settings such as chemical plants and oil and gas facilities. Always verify local compliance requirements before installation.
Yes, the gland uses a 1/2 inch NPT thread for conduit entry. It supports a range of cables including MC, MC-HL, TECK, TC, TC-ER, TC-ER-HL, ITC, ITC-ER, ITC-HL, PLTC, PLTC-ER, and ACIC. Armor range is 0.579–0.872 in and cable range is 0.67–1.00 in, with an outer sheath range of 0.65–1.00 in, enabling broad compatibility in control panels and machinery enclosures.
Access the IF 1890 TMC3 installation sheet for gland-specific guidance and the Eaton TMC3-050-1 datasheet for full specifications. Additional resources include the Crouse-Hinds TMC3 catalog page and the Armored Gland brochure, which provide sizing charts, installation steps, and compliance details to support procurement and field installation.
Using the TMC3-050-1 enhances reliability by delivering a tailored seal for armored and non-armored MC cables, with IP66/NEMA 4X protection that resists dust, water, and corrosion. The 1/2 in NPT entry simplifies installation, reducing labor time. Its armor and cable compatibility lowers the risk of misfit parts, decreasing maintenance costs and accelerating time to production, driving a favorable project ROI.
