Eaton Specification Sheet - EYD101
Rugged material and construction provide high strength and corrosion resistance, translating to longer service life and less frequent replacements in aggressive environments. The drain-equipped design helps expel accumulated moisture, lowering the risk of water ingress that can compromise enclosures and electronics, which in turn reduces maintenance downtime. Vertical sealing position ensures a predictable seal orientation, simplifying installation in tight or vertical conduit drops and minimizing field errors during assembly. The EYD101 carries NEC/CEC compliance and hazardous location ratings (Class I, Division 1 & 2; Class II, Division 1 & 2; Class III) with Group B protection, delivering regulatory assurance for safe operation in explosive atmospheres. Weight and dimensions (4" trade size, 5.25" length/depth, 9.75" height, 5.25" width) support predictable enclosure planning and logistics in manufacturing facilities. Compatibility with Crouse-Hinds sealing fittings ecosystem accelerates procurement and reduces inventory complexity, while installation instructions IF 287 provide clear guidance for correct sealing practice. In short, EYD101 delivers installation efficiency, compliance certainty, and reduced lifecycle costs for industrial hazardous locations.

FAQs
When installing EYD101, ensure correct vertical orientation per sealing position, verify the 4" trade size compatibility with downstream conduit, and follow the IF 287 instruction sheet for installation steps. Verify area classification, Class I/II/III ratings, and maintain proper sealing integrity to prevent moisture ingress and maintain explosionproof performance in hazardous locations.
EYD101 is suitable for Hazardous/Classified Locations with NEC/CEC standards compliance. It carries Class I, Division 1 and Division 2, Class II, Division 1 and 2, and Class III ratings, plus a Group B rating, ensuring protection in explosive atmospheres and alignment with typical electrical safety requirements in oil, gas, and chemical processing facilities.
Yes. The EYD101 is designed for seamless compatibility with the Crouse-Hinds EYD/EZD sealing fittings family, enabling consistent installation practices, standardized seals, and efficient procurement across projects. Always cross-check catalog pages and installation guides to ensure mating components meet the same hazardous-location ratings.
The drain feature allows moisture and condensate to exit the enclosure interface, reducing water exposure to seals and electrical components. This minimizes corrosion risk, helps maintain enclosure integrity, and lowers the likelihood of seal degradation over time—critical for reliability in outdoor or damp installations common in industrial plants.
Regularly inspect the sealing interface for signs of wear or corrosion and verify that the drain path remains unobstructed. Follow manufacturer guidelines and IF 287 instructions for re-sealing after service. Document inspection results as part of a preventative maintenance program to sustain compliance with NEC/CEC and hazardous-location requirements.
