Sirco MC PV 40A 3-Pole DC Isolator Switch 1000VDC | Socomec

The Socomec Sirco MC PV is a 3-pole DC isolator switch rated at 40A and 1000VDC, built for photovoltaic installations. It makes and breaks under load, giving installers a reliable way to isolate DC circuits in solar PV combiner boxes and at inverter DC inputs. Its compact body fits neatly inside a combiner box enclosure without eating into space needed for other components.

Key features of this solar dc isolator switch

• Rating, 40A, 3-pole, 1000VDC
• Switch type, non-fusible DC load break switch, on-load operation
• Breaking capacity, up to 600VDC
• Footprint, compact design suited to combiner box and inverter cabinet installation
• Function, safe isolation of PV circuits under load

Applications

This pv array dc isolator switch is used for DC string isolation within solar PV combiner boxes, and for on-load disconnection at the DC input of solar inverters.

Installation notes

DC solar circuits carry dangerous voltages, so this switch must be installed by a qualified electrician. Installation should comply with IET Wiring Regulations and with the inverter manufacturer's requirements for DC isolation.
