Eaton Specification Sheet - TMCX250 1 NP
Explosion-proof construction provides a robust termination in hazardous environments, reducing ignition risk and ensuring regulatory compliance across NEC/CEC and NEMA 4X requirements. This translates to lower maintenance costs and minimized downtime during plant startups or expansions. The cable range of 1.81-2.72 inches and a seal rating of 1 (S) offer broad compatibility with metal-clad and TECK-armoured cables, enabling faster stocking and fewer part substitutions on site. Nickel-plated brass material delivers superior corrosion resistance in aggressive atmospheres, extending gland life in offshore, chemical, and mining applications. The armoured, barrier, and tray cable configurations support versatile installations in explosion-protected systems, while 2-1/2 in NPT threads standardize mounting across multiple enclosures. Installation efficiency is boosted by documented specs and trusted Eaton-Crouse-Hinds engineering.

FAQs
Begin by verifying enclosure ratings (NEC/CEC Class I, Division 1) and ensuring the enclosure is rated for the intended environment. Clean the entry hole, thread the gland into the 2-1/2 in NPT port, and tighten to the manufacturer’s torque specification. Install the armour glands around the cable, apply any required gaskets or seals (1 S), and verify the seal integrity with a containment test. This process minimizes gas or dust ingress and maintains the explosion-proof rating for ongoing operational safety.
The gland supports a cable sealing range of 1.81 to 2.72 inches, accommodating metal-clad cables with interlocked or continuously welded corrugated armouring, TECK armoured, armoured barrier, and tray cables. This broad compatibility reduces the need for multiple gland types and simplifies spare-part inventories, while ensuring reliable termination for a wide range of hazardous-location installations.
Yes. The TMCX250 is designed for hazardous/classified locations with NEC/CEC standards, including Class I, Division 1, Class II, Division 1, and Class III environments. It also carries a NEMA 4X rating, providing protection against corrosion and harsh weather. These certifications support safe operation in petrochemical, refining, and other high-risk settings.
Use the 2-1/2 in NPT thread to mate with standard explosion-resistant enclosures. Ensure proper torque on the gland to maintain the seal, and select compatible sealing components (1 S) for the cable range. Refer to installation sheets IF 1647 for step-by-step guidance, and consult the 3D CAD drawings for precise mounting and clearance in existing enclosures.
By offering broad cable compatibility, corrosion-resistant nickel-plated brass, and certified explosion-proof protection, the TMCX250 reduces maintenance costs, minimizes downtime, and simplifies regulatory compliance. Its standard 2-1/2 in NPT interface and armoured configurations streamline procurement and installation, delivering long-term reliability in hazardous environments and a clear return on investment through safer, more durable terminations.
