The Power of Three: Solar Photovoltaic Switches
With its truly innovating design, a single Siemens Safety Switch can perform the work of 3 switches by disconnecting up to 3 separate 600V DC circuits with the help of 3 powerful magnets. One of our switches can replace 3 standard switches resulting in lower material and labor costs. Great results, more savings.
Powerful magnets are incorporated into the line base of the switch and are strategically aligned to dissipate the very hot arc generated when a DC circuit is opened under load. This design innovation allows this new disconnects to perform at a level far beyond that of any conventional safety switch on 600V DC circuits.
Siemens enclosed solar photovoltaic switches are available in 30-200A ratings, in Type 1 and 3R enclosures and in both fusible and non-fusible versions. Both negative ground and positive ground switches are available. They are specifically designed for use in photovoltaic applications, which must comply with article 690 of the NEC.
