Schneider Electric 8539 SCG43 Starter Disconnect Combo

Schneider Electric's Square D 8539 SCG43 is a NEMA-style combo starter with an integrated disconnect designed for 600 VAC motor circuits. It belongs to the 8539 family of Type S combination starters (Series D), which consolidate motor overload protection and a manual disconnect in a single enclosure to simplify wiring, protection, and maintenance for industrial applications. Verified configurations documented by Schneider Electric include models such as 8539SCG43V02CS and 8539SCG43V08CP1, both described as combo starters rated for 27 A at 600 VAC in a NEMA-rated enclosure, making them suitable for controlling small- to mid-size motors and providing both overload protection and a disconnect in one device. These assemblies are commonly used in pumps, fans, conveyors, and compressors where a compact, integrated motor control solution improves reliability and reduces panel space. The SCG43 designation places this variant within the SCG series of 8539 combination starters, delivering the convenient combination of protection and disconnect in a single, field-serviceable unit for industrial environments requiring safe, code-compliant motor control.
