FAQs
The ECLK36 S758 is designed with male and female ends for versatile mating to a variety of conduit fittings. Its 1" trade size and 11" overall length simplify routing in restricted spaces, while the 6" flexible segment accommodates misalignment and movement. Ensure a proper seal by following the standard torque and seal guidelines from the Eaton Crouse-Hinds EC catalog page and UL certifications for explosion-proof assemblies. For retrofit projects, verify that the mating fittings are NEC/CEC compliant and rated for Class I, Division 1 service. Always de-energize the area and use correct PPE during installation.
Key specs include 1" trade size, 11" overall length, 2.13" height and width, 2.77 lb weight, and a 6" flexible segment, all in forged brass with a flexible PVC coating. The product is certified for NEC/CEC and Class I, Division 1 hazardous locations, and UL explosion-proof listed. These factors collectively ensure robust enclosure integrity, resistance to moisture and chemical exposure, and reliable electrical continuity under field movement and vibrations typical in chemical plants and oil refineries.
Yes, the ECLK36 S758 is suitable for hazardous locations encountered in marine and offshore environments where exposure to moisture, salt spray, and vibrations is common. Its PVC coating provides additional corrosion resistance, and the forged brass body ensures durable electrical connections. Confirm compatibility with local standards and the vessel’s or platform’s NEC/CEC framework, and ensure all components are UL listed for explosion-proof service in Class I, Division 1 zones.
The ECLK36 S758 carries NEC/CEC compliance and UL explosion-proof certification, along with hazardous-location ratings for Class I, Division 1 (and related divisions). These certifications validate safe operation in explosive atmospheres, ensure proper sealing against ingress, and support regulatory approvals for industrial facilities such as refineries and chemical plants. Always reference the certification documents when preparing project compliance packs and installation qualifications.
Maintenance considerations focus on periodic inspection of the protective coating, seals, and connection integrity after harsh service or vibrations. The PVC coating and forged brass body reduce corrosion and wear, translating to longer service intervals and lower maintenance costs. ROI comes from reduced downtime, faster installation with the 1" trade size and 11" length, fewer spare parts, and faster approvals due to NEC/CEC and UL listings, improving project velocity and asset uptime.
