Eaton Specification Sheet - RDF30J-3
Feature → Business Impact → Application: The RDF30J-3 uses a fused rotary disconnect design that provides reliable isolation and interrupted fault current, reducing arc flash exposure during maintenance and service in motor control centers, conveyors, and machine feeders. This translates to safer, faster maintenance workflows and improved compliance with lockout/tagout procedures. Front/side handle operation and flange mounting enable quick, ergonomic access and secure installation in cramped electrical rooms, minimizing commissioning time and labor costs. Electrical ratings of 30A at 600 Vac / 250 Vdc ensure broad compatibility with common protection schemes, enabling consistent performance in power feeders, pumps, and process equipment. RoHS compliant construction supports regulatory adherence and supplier requirements across tight end-user specifications.

FAQs
RDF30J-3 is designed for flange-mount installations with front/side handle operation, enabling straightforward mounting in standard electrical panels and housings. Its compact dimensions (5.71 in depth, 5.36 in height, 4.14 in width) simplify cutouts and alignment with existing bus bars or protective enclosures, reducing retrofit complexity and panel redesign needs.
Installers should verify power is off and lockout/tagout procedures are in place before starting. Use the flange mounting hardware to secure the unit to a compatible panel opening, then align the front/side handle for accessible operation. Ensure wiring follows the 600 Vac / 250 Vdc, 30A ratings and adhere to local electrical codes during termination and testing.
RDF30J-3 is rated for 30A, with a voltage rating of 600 Vac and 250 Vdc. This combination provides flexibility for a wide range of control circuits, motor starters, and process equipment. The rating supports reliable disconnection under normal and fault conditions, with appropriate protective coordination within the larger protection scheme.
Yes, RDF30J-3 is RoHS compliant, aligning with environmental and regulatory expectations for hazardous substance contents. The provided data does not list additional certifications such as SIL, CE, or IP ratings for this specific model, so integration should be planned around RoHS compliance and the device’s electrical ratings while verifying customer-specific certification requirements.
The RDF30J-3 measures 5.71 inches in depth, 5.36 inches in height, and 4.14 inches in width, with an approximate weight of 3.26 pounds. These metrics help determine cutout size, mounting clearance, and space requirements within control panels, ensuring adequate access for front/side operation and servicing without interference with adjacent components.
