FAQs
EYS10 SA is designed for hazardous locations with Class I Division 1/2, II and III ratings and NEC/CEC compliance. For retrofits, verify that the conduit seals match a 4 in trade size and that vertical or horizontal sealing is compatible with the enclosure or conduit body. Ensure proper torque on fittings, use appropriate gaskets, and follow IF 287 installation guidelines for reliable ignition protection and leak-free seals.
The EYS10 SA carries NEC/CEC standards and NEC hazardous ratings across Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III, plus Canadian certification. These certifications matter because they verify suitability for hazardous locations, influence inspection and maintenance regimes, and help streamline procurement and permitting in North American facilities handling volatile or dusty processes.
Yes. EYS10 SA supports sealing in both vertical and horizontal orientations, giving you installation flexibility in confined or complex layouts. This capability reduces the need for multiple part variants, simplifies spares inventory, and speeds commissioning in control panels, switchgear rooms, or field junction boxes where space is at a premium.
Regular inspection should focus on seal integrity, corrosion resistance, and gasket condition. Inspect the copper-free aluminum body for any signs of wear, verify that the sealing position remains secure, and check for signs of ingress or leakage. Schedule periodic torque verifications and refer to the IF 287 instruction sheet for recommended maintenance intervals and best practices.
By combining robust explosionproof sealing with proven NEC/CEC compliance, EYS10 SA reduces ignition risk and unplanned outages. The copper-free aluminum construction lowers weight for easier handling and maintenance, while the 4 in trade size and dual sealing orientation speed installation. Over time, fewer replacements, simpler inspections, and faster commissioning translate to lower lifecycle costs and improved equipment availability.
