ONCCY DC Isolator is Designed for solar inverter DC side disconnect, Combined with other components, our switches can guarantee complete protection from any form of over-voltage and overloading. With a special instruction for arc extinguishing, we offer increased safety, reliability and longer life.
This is an essential safety switch and is mandated in each photovoltaic power system according to IEC 60364-7-712. The corresponding British requirement comes from BS7671 - Part 712.537.2.1.1, which states "To allow maintenance of the PV convertor, means of isolating the PV convertor from the DC side and the AC side must be provided".
