Square D 9065SS120 U Soft Starter Controller Module

Square D 9065SS120 U is a 3‑pole Solid State Overload Relay and soft‑starter controller designed for use with Square D Type S motor starters. It targets NEMA size 1 starters and provides overload protection for 9–27 A three‑phase motors up to 600 V. The control circuit is powered by 120 V AC, aligning with common control voltages for Type S systems, while the 9065 Series C module integrates with motor logic protections offered by Square D. As a base unit intended for retrofit to Type S starters, it offers a compact form factor that can be installed as part of the starter assembly. Compatible with line voltages up to 600 VAC, this 9065SS120 variant supports applications such as pumps, fans, conveyors, and compressors where reliable solid‑state protection and controlled starting are required. This module is part of Schneider Electric’s Square D 9065 family, and its 9–27 A rating defines the motor current range it can protect. Always confirm that the 9065SS120 fits your specific Type S starter and current requirements before installation.
