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.

Features and Benefits

  • Positive switching Action: All solar switches feature quick make, quick break visible blade switching action and feature factory installed ground bars.

  • Rugged Durability: All copper current carrying parts except for lugs are constructed from copper.  All solar heavy switches are designed to comply with the requirements of article 690 of the NEC are UL listed as UL1741 photovoltaic disconnect switches.

  • Flexibility: Switches are available in 3 pole versions and in both fusible and non-fusible designs. Both Type 1and 3R enclosures are offered. Separate catalog numbers for use on either negative or positive ground systems are available.

  • Ease of Installation: Increased wire bending space and tangential knock-outs speed installation. The unique enclosure design provides a formed out front flange that is easy on the installer's hands and on conductor insulation.

  • Padlockable: All solar switches are padlockable in the OFF position. The door can also be padlocked in the closed position.

  • Availability: Most solar switches are stock items in our warehouses and can be shipped within 2-3 days after order entry.
