• Voltage range, available from 220V to 1000V DC
• Handle, black and grey, padlockable
• Compliance, Class II compliant, grey insulated enclosure

Applications

Fit this switch where two PV strings need DC isolation in one enclosure, on residential or commercial arrays. The IP66/IP67 rating means it can go outdoors, next to the array or at the inverter, wherever a weatherproof disconnection point is needed.

Installation and safety notes

DC solar circuits carry dangerous voltages, so installation must be carried out by a qualified electrician. Match the voltage rating to the maximum open circuit voltage of the connected string. Never operate the switch under load. Lock out the handle before carrying out any maintenance on the DC string.
