Suitable for TN-S, TN-C-S, TT, IT, and photovoltaic 1500VDC and below AC/DC power supply systems with AC frequency of 50/60Hz, 1000V and below. As a lightning equipotential connection, its design basis complies with EN50539-11, GB/T 18802.31, IEC 61643-31. The shell design is installed on a 35mm electrical guide rail. This product has a built-in failure release device. When the surge protector fails due to overcurrent overheating or breakdown, the failure release device can automatically disconnect it from the power grid. At the same time, the visual alarm indicator module changes from green (normal) to red (fault). Kevin wiring method, remote signal output interface, SPI2 and SPI4 series surge protector modules can be replaced online.
