GHK-200,315,400 series low-voltage air isolation reversing switchDetailed product description：

·Scope and Application

GHK-200, The 315400 series low-voltage air isolation reversing switch is suitable for use in power circuits with AC 50Hz, voltage up to 1140V, and currents of 200A, 315A, and 400A respectively. It is used for isolating the main circuit and changing the phase sequence of the power supply under no-load conditions. In the event of a fault, it can be opened with load and has high breaking capacity. It is particularly suitable for forming a kilovolt mining explosion-proof electromagnetic starter.
