SOCOMEC Load Break Switches UL For Photovoltaic Applications From 100 to 2000 A SIRCO PV UL98B

SIRCO PV UL98B non fusible disconnect switches are heavy duty switches that break and make DC photovoltaic circuits on and off load. They are suitable for use in accordance with NEC Art. 690 Photovoltaic Installations. These switches are extremely durable and are tested and approved for use in the most demanding applications. They are available in 2, 3, 4, 6 and 8 poles for all configurations from one to 4 circuits and can be used in all types of earthing systems (floating or grounded systems, single or double polarity switching), in order to suit all your requirements. Advantages Optimise your investment High switching performances means less poles in series to reach the operating voltage, consequently: • Less bridging bars required, limiting installation costs and time. • Less heat dissipation, making it possible to be installed in a smaller enclosure. Guarantee safety over time SIRCO PV are extremely robust products, with all casings made from fiber glass reinforced polyester materials that allows: • High mechanical withstand. • High stability to temperatures (RTI of 130 °C). • High dielectric performance (high CTI / tested according to ASTM D 2303). Take advantage of an innovative design The SIRCO PV are able to operate on and off load up to 500 VDC per poles, providing extremely compact solution: • 1000 VDC (UL 98B) on a 2 poles switch. • 1500 VDC (IEC 60947-3) on a 3 poles switch. • Up to 4 circuits each at 1000 VDC on an 8 poles switch. Reliability and performance Our range of SIRCO PV load break switches is compliant with UL98B and IEC 60947-3 standards and have been tested above standards expectation, ensuring no critical current. They are as well able to withstand 10 kA, 50 ms, allowing the use of any overcurrent protection device for line protection.
