Eaton Specification Sheet - EYS3 SA
Copper-free aluminum housing provides durable, corrosion-resistant protection with a lighter footprint than steel fittings, improving handling in the field and reducing enclosure wear over time. This translates to lower maintenance costs and easier inventory management for service teams. The EYS3 SA supports a standard 1" trade size used across panel boards, motor control centers, and process equipment, enabling straightforward retrofits and consistent performance in demanding environments. Vertical sealing position ensures a predictable seal, reduces installation errors, and streamlines retrofit work on existing conduits. By eliminating sealing in non-vertical orientations, field technicians avoid misalignment and patchwork sealing, saving inspection time and minimizing leak paths. This characteristic pairs well with Eaton's EYS/EZS explosionproof family, allowing consistent performance across different enclosures and installation heights while preserving enclosure integrity. Designed for field replacement, the 1.75 in length and 4.31 in height fit common enclosures. Copper-free aluminum resists chemical corrosion, lowering maintenance costs. Vertical sealing reduces retrofit misalignment and aligns with Eaton's EYS/EZS family. These combined features deliver reliable explosionproof protection with reduced lifecycle costs in hazardous locations.
