Eaton Specification Sheet - TMCX3112
Feature: Armoured barrier and non-armoured barrier gland options provide versatile sealing for both shielded and unshielded cable entries. Business Impact: Reduces inventory complexity and simplifies field retrofits, avoiding the need for separate glands. Application: TECK armoured tray cables in hazardous locations such as chemical plants and refineries can be sealed with confidence. Feature: Aluminum construction lowers weight while resisting corrosion, aiding ease of handling and reducing fatigue during installation. Business Impact: Improves installer productivity and enclosure integrity, particularly in tight spaces. Application: Favorable for overhead or vertical installations where weight matters. Feature: 1" NPT thread size and compatible threading simplify mounting with standard conduit fittings. Business Impact: Shortens commissioning time and minimizes field adaptation costs. Application: Broad compatibility with common electrical fittings in control panels and junctions. Feature: Armor range and outer sheath compatibility (0.80-1.12" and 0.85-1.31") ensure a snug, reliable seal. Business Impact: Reduces leak paths and maintenance cycles, supporting longer service life. Application: Works with TECK armoured and metal-clad tray cables in dynamic industrial environments. Feature: Explosion-proof protection and hazardous-location ratings. Business Impact: Supports regulatory compliance and safer operation, mitigating risk in volatile environments. Application: Essential for oil & gas, chemical processing, and fuel infrastructure facilities. Feature: UL certification, installation instructions, and spec sheet availability streamline procurement and field setup. Business Impact: Improves reliability of installation documentation and reduces misapplication risk. Application: Accessible through Eaton/UL resources for quick reference during project planning and commissioning.

FAQs
The TMCX3112 is designed for use on TECK armoured tray cables in hazardous/classified locations. Plan for a 1" NPT gland interface, ensure armor and outer sheath ranges (0.80-1.12" and 0.85-1.31") match the cable, and follow IF 1184 installation guidelines to maintain explosion-proof integrity and NEC/CEC compliance.
TMCX3112 supports NEC/CEC standards with Hazardous/Classified Locations ratings and a NEC hazardous rating of Class I, Division 1; Class II, Division 1; Class III, plus a NEMA 4 enclosure rating. This combination ensures regulatory compliance and suitable performance in demanding environments.
Yes. The gland is specifically rated for TECK armoured tray cables and uses a 1" NPT thread size, enabling straightforward integration with standard conduit fittings and enclosure entries commonly found in industrial control panels and hazardous-area installations.
Key dimensions are 4.07 in in length, 2 in height, and 2 in width, with a weight of 0.68 lb. The thread size is 1", and the outer sheath and armor ranges are 0.85-1.31" and 0.80-1.12" respectively, supporting precise fit and efficient installation.
By providing explosion-proof sealing with armoured and non-armoured barrier options, the TMCX3112 reduces leakage risk and improves reliability. Its NEC/CEC and NEMA 4 compliance minimize compliance-driven downtime, while the aluminum construction lowers weight for easier handling, reducing installation time and long-term maintenance costs.
