The 6NTG series isolating switch is suitable for circuits with AC 50Hz, rated voltage of 400V and below, and rated current of 630A~1600A. It is used for infrequent manual making and breaking of circuits, with the 690V specification product only for electrical isolation; its normal operating conditions are: altitude not exceeding 2000 meters, ambient temperature not higher than 40℃ and not lower than -5℃, relative humidity not exceeding 95%, and it shall be used in an environment free of explosive hazardous media and rain/snow erosion. Note: If it is expected to be used in an environment where the ambient air temperature is higher than +40℃ or between -5℃~-45℃, users shall inform the manufacturer when placing an order. The switch adopts an accelerated closing mechanism with spring energy storage in place and rapid instantaneous release, as well as a parallel double-break contact structure that makes and breaks simultaneously, greatly improving electrical and mechanical performance.
