Solar and other renewable source standalone power systems and large capacity emergency supply systems require special considerations. High fault capacities exist and voltages range from 12 volts to 750 volts DC.

DC switching and protection is handled capably by traditional AC devices up to 48VDC and sometimes higher. With the Efen range of disconnectors and fuses ably supported by an experienced team, solutions in all voltages up to 750VDC can be provided. Special assemblies using these off-the-shelf disconnectors can be provided to suit special applications for direct wall mounting.
