Square D 8502SF0 Reversing Starter

Square D 8502SF0 Reversing Starter is a NEMA Size 4 reversing motor starter in Schneider Electric's Square D Type S family, designed for forward and reverse operation on three‑phase motors with a 480 VAC coil. In reversing service, the starter is typically formed from two 8502S contactors mechanically interlocked to provide bidirectional rotation when wired with the appropriate control circuitry. The 8502 family is part of Type S motor starters and supports 3‑pole operation, with a 480 VAC coil compatible with standard 50/60 Hz power. This configuration is used in industrial equipment where reversible motor control is required, such as conveyors, fans, and pumps. The interlock between the two contactors prevents simultaneous energization of opposing directions, ensuring safe forward/reverse operation.
