Product description
XK1-D series surge protector for AC 50HZ/60HZ, 380V and below the TT, IT, TN-C-S and other power supply system can be used as when the lightning equipotential connection, designed to meet the GB18802.1-2002 and IEC61643-1:1998 technology standards, housing design and installation in 35mm electric rail, the product inside the failure from the device, when the power supply protection due to over-current and over-temperature, breakdown failure, failure from the device can automatically be separated from its from the grid, and visual alarm indication module can be replaced in the working voltage conditions.
Product features
