Manufacturer: Eaton (Cutler-Hammer) Catalog Number: R9K3100FJ Product: K-Frame fusible rotary disconnect switch PUBLISHED RATINGS Current Rating: 100 A Voltage Rating: 600 VAC Poles: 3 Frame: K-Frame Fusible: YES. This is a FUSIBLE disconnect and requires fuses to be fitted. UL Fuse Class Accepted: Class J Short Circuit Current Rating: 200 kA Standard: Built to UL98 Actuator: rotary handle Terminals: lug terminals Contact Design: double break contacts, giving complete fuse isolation when the switch is in the OFF position Dimensions as catalogued: 4.81 in. L x 5.78 in. W x 7.32 in. H FUSIBLE, NOT NON-FUSIBLE - FLAGGED: this record's title describes the item only as a "100 Amp Rotary Disconnect Switch". The catalogue number R9K3100FJ is the FUSIBLE version taking Class J fuses; the trailing FJ denotes the J-fuse build. A buyer expecting a non-fusible switch would be getting the wrong device, and the fuses are a separate item. The title also lists 250VDC; Eaton's catalogue entry states the 600 VAC rating, and a DC rating is not confirmed from the manufacturer source, so no DC figure is asserted here. MOUNTING, UNRESOLVED: authorised distributor listings for this catalogue number disagree on the mounting method, one giving DIN rail mount and another giving panel mount. Eaton's own specification page could not be retrieved to settle it, so no mounting method is stated here. Confirm against the unit and against Eaton's specification sheet before it is quoted into a panel design. UNPUBLISHED / NOT STATED HERE: weight, the DC voltage rating, enclosure or open-construction detail, and the shaft and handle accessories required to complete a door-mounted installation. These are ordered separately in the R9K range and are not stated on the sources consulted. Spec Basis: Eaton SKU catalogue entry for R9K3100FJ and authorised Eaton distributor catalogue listings (RS Components, WESCO and Platt Electric Supply) for the current and voltage ratings, pole count, K-Frame designation, Class J fusing, 200 kA short circuit rating, UL98 standard, rotary handle actuator, lug terminals, double break contact design and catalogued dimensions. Conflicting mounting descriptions are reported rather than resolved by guesswork.
