Product description
XK1-B series surge protector for AC 50HZ/60HZ, 380V and below the IT, TT, TN-S, 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 is built out of device failure, when the power supply due to over-current and over-temperature protection failure, breakdown, 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
1, without interruption to replace the protection unit
2, maximum 100KA (8/20 μ S) lightning current impuls
3, the reaction time of less than 25 ns
4, the visual window color protection work status, green (normal) and red (fault)
The installation position and Application
(B/4) level of surge protection device (SPD) for protection, such as lightning equipotential connection, installed in the LPZ20A or LPZOB area, LPZ1 area at the junction, is usually installed in the inlet line low-voltage main distribution cabinet office wear tube.
(B/2) is usually installed in the overhead line into low-voltage main distribution cabinet, by a monopole combined into the power system configuration.
