Reliable Power Source Changeover

Changeover switches such as the Lovato GAZM040ET8 allow operators to manually select between two power supplies while providing a defined off position for isolation. This makes them suitable for applications where dependable source selection is required without automatic transfer equipment.

The four-pole configuration enables switching of three-phase conductors and neutral, making the unit well suited to generator changeover systems, building services and industrial installations. Its enclosed IP65 construction provides a practical solution for local switching points and control panel environments.

Typical Applications

• Mains-to-generator changeover systems.
• Dual supply source selection.
• Industrial machinery power switching.
• Control panel and automation systems.
• Commercial building electrical installations.
• Manufacturing and process plant distribution circuits.
