FAQs
RSMP22 is designed specifically for the Eaton Crouse-Hinds RS/RSS series. It offers a 4-1/2 x 4 inch footprint with two 3/4 inch trade-size hubs, matching the enclosure size and hub configuration used in RS/RSS installations. This compatibility reduces the need for extra adapters or custom fittings, speeding up panel builds and service replacements.
RSMP22 inherits NEC/CEC compliance and a NEMA 3 rating, with Ordinary/Non-Hazardous area classification. UL certification for the RS/RSM/RSS family supports these claims, ensuring the hub plate supports safe, code-compliant installations in non-hazardous environments. These certifications minimize regulatory risk and rework during audits or inspections.
RSMP22 is specified for Ordinary/Non-Hazardous Locations with a NEMA 3 rating, making it suitable for indoor use and protected outdoor areas that are non-hazardous. It is not rated for truly hazardous environments, so for outdoor or corrosive sites, verify additional protective measures or alternate enclosures from the RS/RSS family.
RSMP22 provides a compact 4-1/2 x 4 inch footprint with 3/4 inch hubs, enabling cleaner conduit routing and fewer accessory parts. The feraloy iron alloy body offers durability against impact and corrosion, reducing maintenance. Its standardized dimensions translate to faster onboarding for technicians and less field modification, improving project timelines.
The hub plate reduces installation time and inventory complexity by aligning with RS/RSS kits and standard hub sizes. Durability from ferraloy alloy lowers replacement costs, while NEC/CEC compliance and NEMA 3 protection mitigate risk and rework. Overall, expect shorter project cycles, fewer field issues, and lower total cost of ownership across panel builds.
