Siemens Introduces Solar Safety Switch


Siemens Industry Inc. has introduced a heavy-duty, UL-listed, three-pole solar disconnect switch that is able to control three separate 600 VDC circuits. Available in 30-, 60- and 100-amp ratings, the Solar Photovoltaic Type VBII Safety Switch lowers equipment and installation costs by doing the work of three traditional switches in similar solar applications, according to the company.

The switch uses magnets that are strategically located within the line bases to quickly disperse and extinguish arcs when negative-ground 600 VDC circuits are opened under load. Available in fusible and non-fusible versions, the Solar Photovoltaic Type VBII Safety Switch comes in Type 1 and 3R enclosures for indoor and outdoor installations.

A factory-installed ground bar is standard, and a rolled out front flange prevents injury to conductor insulation and installers' hands, Siemens adds. A metal handle with a large plastic grip offers positive stop in both the ‘on’ and ‘off’ positions.

Two- and three-point mounting provisions are also standard, as are large top, bottom and side gutters to help facilitate wiring.
