GA040ET8 Lovato 4P 40A CHANGE-OVER SWITCH

Why Choose the Lovato GA040ET8 4-Pole 40 A Change-Over Switch?

The Lovato GA040ET8 is a robust four-pole 40 A 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 reliable switching performance with a compact design suitable for control panels, switchboards and machinery.

The GA040ET8 is designed for AC applications and provides four-pole switching, making it suitable for systems where all four conductors need to be switched. Its 40 A conventional free-air thermal current, high insulation rating and industrial utilisation categories make it suitable for a broad range of power switching duties.

With rated operational currents of up to 40 A at 690 V AC for AC-21A and AC-22A duties, the GA040ET8 provides dependable performance for resistive and mixed loads. For AC-23A motor and highly inductive load applications, it is rated at 40 A at 400 V AC and 25 A at 500–690 V AC. Installation is flexible, with mounting by screws onto a plate or directly onto a 35 mm DIN rail.
