The GSP9 series SPD is designed for TN-S, TN-C-S, TT, IT, and other AC 50/60Hz, 380V power supply systems. It is typically installed at the boundary of LPZ1 or LPZ2 and LPZ3 zones.
The SPD features a visual window indicator. When the device is operating normally, the window displays green. In the event of a fault or breakdown due to overheating or overcurrent, the indicator turns red, indicating that the module needs replacement.
Yes, the GSP9 utilizes a modular design that allows the protective modules to be replaced online even when operating voltage is present, minimizing system downtime.
It is designed for easy and convenient installation on standard 35mm DIN rails.
The GSP9 surge protective device can operate reliably within a temperature range of -40°C to +80°C.
Yes, it features integrated internal over-current and over-heat protection, combined with temperature control open circuit technology, ensuring safe separation from the power system during failure.
