Bussmann by Eaton RDF100J-3 F Disconnect Switch

The RDF100J-3 Fused Rotary Disconnect Switch from Bussmann by Eaton is a three-pole, Class J fuse-compatible disconnect designed to provide visible, fused isolation for three-phase circuits rated up to 600 VAC (with a 250 VDC rating). It carries a 100 A continuous current rating, making it suitable for motor loads, power distribution panels, and other industrial equipment where fused isolation is required. With front- or side-handle operation and flange mounting, this unit is intended for installation in switchgear, panel boards, MCCs, and other enclosures that require a dedicated isolation device. The RDF100J-3 is part of Eaton’s Bussmann RDF series of fused rotary disconnect switches and is designed to accept Class J fuses to protect downstream equipment. Typical applications include three-phase motor circuits, service entrances, and other industrial power systems that require a fuse-protected disconnect at 100 A, 600 VAC, and 250 VDC ratings.
