Why Choose the Lovato GX329566U 3-Position Star-Delta Changeover Rotary Cam Switch?
The Lovato GX329566U is a specialised 3-position star-delta (Y-Δ) rotary cam switch designed for industrial motor-control applications requiring manual changeover between defined starting and running states. Part of the Lovato GX32 series, it combines a robust square-shaped contact-block construction with a mechanically indexed rotary cam mechanism for dependable motor-control switching.
The three-position arrangement provides the switching sequence required for star-delta motor control, allowing an operator to move through the defined selector positions using a single rotary handle. Star-delta switching is commonly used with suitable three-phase motors to reduce starting current by initially connecting the motor windings in star before changing them to delta for normal operation.
Built on Lovato's GX32 platform, the GX329566U has a conventional free-air thermal current rating of 32 A, an IEC/EN rated insulation voltage of 690 V and a rated impulse withstand voltage of 6 kV. The U front-mounting configuration uses a black operating handle, while the GX32 range provides IP65 frontal protection for demanding industrial panel installations.

Manual Star-Delta Switching for Three-Phase Motors
Star-delta starting is used with suitable three-phase induction motors to reduce the electrical demand during starting. The motor windings are initially connected in star (Y), reducing the voltage applied across each winding and therefore reducing starting current and starting torque. Once the motor has accelerated, the switch is moved to the delta (Δ) operating state for normal running.
The Lovato GX329566U performs this switching through a mechanically defined cam programme, allowing the required motor connections to change as the selector is moved between its three positions. The switch should be wired according to the applicable Lovato switching diagram and used only with motors and installations suitable for manual star-delta starting.
Typical Applications
- Manual star-delta starting of suitable three-phase motors.
- Industrial motor-control panels.
- Pumps, fans and ventilation equipment.
- Compressors and process machinery.
- Machine tools and manufacturing equipment.
- Conveyors and material handling systems.
- OEM machinery with manual motor-starting controls.
- Industrial applications requiring a robust 3-position Y-Δ selector.
