Solarmi DS240S-280DC surge arrester, 350Vdc, 50A, CE

Xtend Solarmi DS240S-280DC

Surge arrester designed for the protection of photovoltaic devices . Due to the nominal input voltage of 280 V and the maximum voltage of 350 V, it is suitable for use with GridFree GF-SUN solar controllers and inverters . Max. operating current 50 A (gL/gG type fuses).

The surge arrester contains a thermal disconnector, a varistor with a thermal fuse, an optical fault indication and remote signaling of the arrester status. The arrester is mounted on a DIN rail and has a modular structure - a basic part and exchangeable modules. The exchangeable module allows for easy and quick replacement of a damaged part.

The DS240S-280DC surge arrester is designed to protect small and medium-sized stand-alone photovoltaic power plants with a maximum input of 350 V. It serves as the main protection of the system against surge peaks caused by, for example, lightning strikes. It is installed on the line from the solar panels before entering the controller or inverter. It is connected to these devices in parallel with ground.

The surge protector will conduct the surge potential to ground via the ground terminal block, thus protecting other devices in the system.
