GA063SAET8 Lovato 4P 63A CHANGE-OVER SWITCH

Why Choose the Lovato GA063SAET8 4-Pole 63 A Change-Over Switch?

The Lovato GA063SAET8 is a robust four-pole assembled change-over switch designed for manual switching between two electrical supplies or circuits in industrial and commercial power distribution systems. As part of the Lovato GA switch disconnector series, it combines two switching devices with a mechanical interlock to provide dependable change-over operation.

With an IEC conventional free-air thermal current of 63 A, the GA063SAET8 is suitable for AC switching applications where reliable source selection and circuit isolation are required. Its four-pole configuration allows all four conductors of the applicable circuit to be switched together, making it particularly useful in three-phase systems where neutral switching is required.

The GA063SAET8 offers an AC-21A operational current of 63 A at 400 V and an AC-23A operational current of 45 A at 400 V, with an AC-23A operational power rating of 22 kW. Installation is flexible, with mounting by screws onto a plate or onto a standard 35 mm DIN rail.

Reliable Manual Change-Over for Power Distribution

Change-over switches provide a controlled means of selecting between two electrical supplies or circuits while preventing simultaneous connection of incompatible sources. They are commonly used where equipment must be transferred between a normal and alternative supply, or where two circuits require mechanically interlocked selection.

The Lovato GA063SAET8 combines a four-pole switching arrangement with robust electrical and mechanical characteristics for industrial applications. Its high mechanical endurance, broad utilisation-category ratings and flexible mounting options make it suitable for integration into switchboards, control panels and power distribution assemblies.

Typical Applications

• Main and alternative power supply selection.
• Generator and mains change-over systems.
• Industrial electrical switchboards.
• Three-phase distribution systems requiring neutral switching.
• Machine and process control panels.
• Commercial and industrial power distribution assemblies.
