PRSI-F photovoltaic switch with the function of emergency short circuit of panels
Compact PRSI switches are designed for use in photovoltaic installations. With 0-I knob position they work as main disconnectors, while in the 0-II position, they can, within the range of rated parameters, transfer short-circuit currents during an emergency short-circuit of photovoltaic panels in case of fire.
