Schneider Electric 8536WFO3V02S Vacuum Starter

Schneider Electric’s Square D 8536WFO3V02S is a three‑pole, nonreversing vacuum starter (Class 8536, Type W) designed to switch motors when overload protection isn’t provided separately. Packaged as a NEMA Size 4 open enclosure, this 8536WFO3V02S is configured for 600 VAC motor circuits and carries a 135 A rating on the line side, making it suitable for mid‑range industrial motors. The control coil is 110/120 VAC (V02), enabling direct control from common low‑voltage controls in both 50/60 Hz environments. This vacuum starter is intended for direct motor control in general‑purpose industrial applications—pumps, fans, conveyors, and other 3‑phase loads—where a robust vacuum switching device is preferred for starting and stopping without separate motor protection. As part of the Square D Class 8536 family, the W‑series vacuum starters provide nonreversing operation for simple on/off control and are typically used when motor overload protection is not provided by a separate overload relay. The 8536WFO3V02S variant is designed to pair with standard control circuitry and is offered by Schneider Electric within the Square D portfolio for reliable, legacy‑friendly motor control in commercial and industrial settings.
