Eaton TMC10402 BR Cable Gland - NEMA 4 NEC/CEC
Part Number: TMC10402 BR
Quick Summary
Cable gland is a sealing and strain-relief fitting for terminating metal-clad cables in electrical enclosures. Engineers often struggle with moisture ingress, dust intrusion, and inconsistent gland sizing that slows panel assembly. The Eaton Crouse-Hinds TMC10402 BR delivers a rugged brass, armoured gland rated for NEMA 4 and NEC/CEC environments, with UL-listed armour options. Designed for TECK corrugated or interlocked steel and aluminum armor and 4 inch NPT threads, it streamlines installation while maintaining safety and long-term reliability. This combination reduces field rework, extends equipment life, and supports compliant panels for ordinary/non-hazardous locations. Typical installations include machine rooms, process panels, and motor control centers where a precise armor and outer sheath fit (armor 3.50-4.02 in; outer sheath 3.58-4.28 in) is required.

Eaton Specification Sheet - TMC10402 BR
Brass construction and armoured design deliver superior corrosion resistance and mechanical strength, reducing flange wear and seal degradation over time. This translates to lower maintenance costs and longer service intervals in harsh environments. The gland accommodates TECK corrugated or interlocked steel, or aluminum armor, making it suitable for a range of metal-clad cable configurations in control panels and MCCs. A 4 inch NPT thread enables straightforward mounting to common enclosure entries, simplifying stock management and spare parts handling while reducing installation time and risk of leaks. The armor range of 3.50-4.02 inches and outer sheath range of 3.58-4.28 inches ensures a precise fit, eliminating gaps and ingress points that compromise performance. Compliance and safety are reinforced by NEMA 4 rating and NEC/CEC standards, with UL certification support for the armoured variant, accelerating validation and commissioning. Installation and fitment advantages include reliable sealing and strain-relief for high-density cables, faster panel builds, fewer reworks, and clearer documentation for inspections. In industry contexts such as manufacturing, process automation, and machine building, a standardized gland that supports multiple armor types reduces SKU fragmentation and logistics costs, streamlining procurement and maintenance workflows.
