Square D 8536-F0-1-S4 Motor Starter Contactor

Square D 8536-F0-1-S4 is a NEMA Type S motor starter contactor in size 4 from Square D (Schneider Electric), designed for three‑phase motor control in industrial panels. It provides three‑pole switching for full‑voltage starting and stopping of motors, a common configuration for mid‑size motor loads. The coil voltage is 115–220 V AC, enabling direct interfacing with standard control circuits and flexibility across a range of supply voltages. As part of the Type S family, 8536 starters are offered in non‑reversing and reversing configurations across multiple sizes, with size 4 representing a mid‑range option that shares mounting and terminal practices with other 8536 devices. These starters are intended to switch motor loads while overload protection is provided by separate devices as required in typical electrical control circuits. This lineage of Square D motor starters is well established for reliable motor control in industrial applications, compatible with Square D/SCHNEIDER Electric control systems and broad field wiring practices.
