The Solar DC disconnect switches of the HDC series were developed specifically for photovoltaic systems on an industrial scale and enable safe, precise disconnection of DC circuits – even at high currents and voltages. As a core component in the generator connection box they are a central element of modern trunk systems that bundle multiple string outputs, shorten cable runs and make the overall installation more efficient.

With support for up to four DC inputs, optionally integrated gPV fuse links and modular connection variants, the disconnect switches can be tailored precisely to the design requirements of your PV system. Thanks to high switching capacity up to 1000 V DC (C&I) and 1500 V DC (utility scale), they ensure maximum safety and reliable system availability.

The robust, fully insulated enclosures with high impact resistance and UV resistance are ideal for demanding industrial and outdoor environments. Thanks to compatibility with aluminium and copper conductors, the PVDC disconnect switches integrate seamlessly into existing and new trunk architectures. The HDC series thus offers maximum operational safety, flexibility and efficiency for every industrial application.

With their high switching capacity, robust design and modular configurability, the HISbox PV DC disconnect switches are the ideal choice for industrial trunk solutions. They reduce installation costs, increase system availability and ensure the highest operational safety in demanding system concepts.
