Eaton Specification Sheet - TMCX350 1
Armoured protection translates to a lower likelihood of cable ingress in hazardous settings, delivering a tangible reduction in unplanned downtime and maintenance costs. The gland supports armored barrier, tray cable, and TECK armoured configurations, enabling a single gland to cover multiple cable families and simplifying procurement and stocking. A 3-1/2" NPT thread size coupled with a robust aluminum body provides a lightweight yet durable enclosure that resists corrosion and vibration as found in refineries and chemical plants, improving total cost of ownership. The 1 (S) sealing range and a cable range of 2.62-3.78 inches ensure reliable ingress protection across common cable assemblies, while the TSC compound barrier offers stable performance under harsh chemical exposure. Installation is streamlined by standard formats and compatibility with standard conduit entries, reducing commissioning time and ensuring regulatory alignment. These features support safer operations, faster project timelines, and lower long-term maintenance burdens in demanding environments.

FAQs
The TMCX350 1 is designed to support armored barrier, tray cable, and metal-clad cables with interlocked or welded armouring types. Its 2.62-3.78 inch cable range and 3-1/2 inch NPT entry diameter enable versatile terminations across standard industrial installations. In practice, you can unify gland procurement for mixed cable types, reducing inventory complexity while maintaining a consistent sealing performance in hazardous locations.
This gland carries NEC/CEC standards alignment, UL certification for use in hazardous locations, and a NEMA 4X enclosure rating. It is classified for Hazardous/Classified Locations, ensuring safe operation in environments with explosive atmospheres. These certifications collectively support regulatory compliance, safe maintenance practices, and reduced risk in chemical plants, refineries, and mining facilities.
The 3-1/2" NPT thread size aligns with common conduit penetrations found on industrial enclosures. When installing, ensure proper torque per gland specification to maintain the 1 (S) sealing range and to preserve ingress protection. Use appropriate thread sealant or Teflon tape and verify the gland’s seating against the enclosure face to prevent any ingress path, especially in vibration-prone or corrosive environments.
Yes. The aluminum construction with TECK and armoured options, combined with a TSC barrier, provides robust protection in outdoor and chemical-exposed environments. The NEMA 4X rating further confirms suitability for washdown and potentially harsh chemical exposure, while the hazardous-location certifications ensure safe operation in explosive atmospheres commonly found in outdoor industrial sites and processing plants.
Using the TMCX350 1 typically yields lower maintenance costs due to enhanced ingress protection and reduced corrosion risk from aluminum construction. The gland’s compatibility with multiple cable types reduces spare-part requirements, while NEC/CEC and UL certifications shorten compliance-related project delays. Over the equipment lifecycle, these factors translate to improved uptime, safer operations, and a favorable return on investment from reduced downtime and maintenance cycles.
