Sylvania Clark T30U031 Reversing Starter

The Sylvania Clark T30U031 reversing starter is a size-1, three-pole motor controller built to reverse the direction of a three-phase motor. Rated for 10 HP, it operates with a 110–120 VAC control coil (coil designation A61), making it suitable for standard low-voltage control circuits in industrial panels. This reversing starter is designed for applications where forward and reverse operation is required, such as conveyors, pumps, fans, and hoists, and pairs with conventional overload protection in a motor control scheme. The compact form factor and Clark/Joslyn lineage make it a practical replacement or retrofit option for legacy equipment that uses the T30U family of reversing starters. In installations, the T30U031 typically integrates with a control circuit that provides start/stop signals and a separate overload relay, enabling safe, directional switching without modifying the motor wiring. Its compatibility with common Clark cataloging and spare parts ecosystems helps ensure ongoing serviceability in facilities with older machinery.
