Lovato GA160ET8 is a four-pole 160 A assembled AC change-over switch designed for reliable manual source selection and isolation in industrial and commercial power distribution systems.
£387.13
The Lovato GA160ET8 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 provides dependable source selection with an I-0-II change-over arrangement for applications requiring controlled transfer and isolation.
With an IEC conventional free-air thermal current of 160 A, the GA160ET8 is suitable for substantial AC power distribution loads. Its four-pole configuration enables simultaneous switching of four conductors, making it particularly useful for three-phase installations where the neutral conductor also needs to be switched during source change-over.
The GA160ET8 provides an AC-21A operational current of 160 A at 400 V and an AC-23A operational current of 125 A at 400 V, with an AC-23A operational power rating of 55 kW at 400 V. Installation is flexible, with fixing by screws onto a mounting plate or onto a standard 35 mm DIN rail.
Change-over switches provide a controlled means of selecting between two electrical supplies while maintaining electrical isolation between the sources. This functionality is commonly used for mains and generator selection, alternative supply arrangements and industrial installations where loads need to be transferred manually between two independent circuits.
The Lovato GA160ET8 combines a four-pole switching arrangement with robust electrical characteristics for demanding power distribution applications. Its high current ratings, substantial short-circuit capability and flexible mounting options make it suitable for integration into industrial switchboards, control panels and power distribution assemblies.
