Why engineers spec these DC switches
Made for DC, not adapted
Socomec DC switches break 750 VDC per pole and carry UL 98B, UL 508I and IEC 60947-3 ratings for DC-21B and DC-PV2 duty.
Fits tight combiner boxes
SIRCO MC PV has a compact frame with factory fitted bridging bars, so it drops into combiner boxes and solar inverters.
Mount it your way
Choose DIN rail, back plate, door or Quick Fix mounting. Front operation with direct position indication and visible contacts.
Holds up outdoors
INOSYS LBS runs from -40°F to +122°F with no derating to 131°F, and is tested for vibration, shock and 95% humidity.
Help choosing the right part
Send your voltage, current and poles. We match the frame, poles and operator, and send CAD files and manuals.
One source for the DC circuit
Switches, PV fuse holders, ESS fuses, busbars and power monitoring all come from the same supplier.
PV and DC disconnect switches we supply
ValuAdd distributes Socomec load break and disconnect switches built for photovoltaic and DC circuits. Ratings run from small combiner box switches up to 2000 A motorized units at 1500 VDC, so the same range covers strings, inverters and battery racks.
Every switch is quoted to your application. Give us the DC voltage, rated current, pole count and how it will be operated, and we will confirm the part numbers and send documentation.

Frequently asked questions
How much does a PV disconnect switch cost?
Pricing is available on request. Cost depends on the rated current, DC voltage, number of poles, operator type and mounting, so we quote each request after we see your specs.
What DC voltage and current can these switches handle?
SIRCO MC PV covers 20 A to 40 A at 600 to 1500 VDC. INOSYS LBS UL 98B covers 10 A to 1200 A at 1000 to 1500 VDC, with up to 2000 VDC available. SIRCO MOT DC reaches 2000 A at 1500 VDC.
Are the switches UL listed for PV work?
Yes. SIRCO MC PV is built to UL 508I and IEC 60947-3 with specific photovoltaic testing. INOSYS LBS is UL 98B listed and meets IEC 60947-3 for DC-21B and DC-PV2 utilization categories.
Will it fit inside a combiner box?
SIRCO MC PV uses a compact frame designed for combiner boxes and solar inverters, with factory fitted bridging bars and DIN rail, back plate, door or Quick Fix mounting options.
Do you also supply PV fuses and fuse holders?
Yes. We supply Socomec RM PV UL modular fuse holders for gPV fuses up to 30 A at 1000 VDC, and FP ESS DC fuses up to 1500 VDC and 250 kA for energy storage.
