Technoelectric SD2-100-RR Disconnect Switch

The Technoelectric SD2-100-RR is a three-pole, 100 A, non-fused load-break disconnect switch designed to provide safe electrical isolation in industrial power distribution and motor-control systems. It operates up to 600 VAC with an AC-22A / AC-23A interrupt rating and a 5 kA SCCR, making it suitable for manual load switching in control panels, motor control centers, conveyors, packaging lines, HVAC equipment, machine tools, and OEM automation gear. Mounting options include 35 mm DIN rail or panel mounting, a rotary red emergency-style handle, and IP20 protection on the switch (IP65 when configured with a door-mounted handle); the contact design features double-break contacts per pole, with optional 1 NO + 1 NC auxiliary contact block. The product is UL 508 Listed and RoHS compliant, and while discontinued, it remains compatible with common replacements such as the Socomec SIRCO M 100A, Technoelectric SD2-125-RR, and Technoelectric SD2-100-BR.
