Fuses & Surge Arrestors for Solar Power Systems

Known reserves of fossil fuels – today the world’s main energy resource – will be depleted by the end of this century if no alternatives are found in the near future. One of the environment friendly developments is solar energy among the others – such as wind power, hydropower, aerothermal and geothermal sources. Solar power solutions need special circuit protection needs. Any installation, whether it is a stand alone solar array with a back-up generator set or a grid connected one, is vulnerable to fault currents or lightning. Today fuses and surge arrestors are the most effective ways of protecting the wiring and all the electrical equipment in the PV (photovoltaic) system. But the protection must be designed, dimensioned, tested and adapted to the specific features of solar applications. At Ferraz Shawmut, the specialist in protection specially designed for power generation and distribution, offers precise solutions, with dedicated products known as Helio range comprising of: Helio Box; Surge Trap; Helio Fuses for different voltages; and Helio Switch. Fuses shield the cables between strings of modules from damage. Faulty circuits are isolated and the system can keep on generating power. These fuses are designed to clear low fault currents.
