Why Choose the OTDC315FV11 [1SCA158178R1001]
This two-pole DC switch-disconnector is optimised for utility-scale photovoltaic systems operating at 1500V, with a current rating from 315 to 630A. Its advanced design delivers enhanced efficiency and performance while reducing physical dimensions, supporting manufacturers in meeting the growing demand for 1500V DC solutions. The two-pole configuration minimises switching losses by up to 35%, improving overall system efficiency. Compact at 150mm wide and 122mm high, the OTDC range is up to 30% smaller than traditional alternatives, enabling more compact combiner box and inverter designs. This model is specifically designed for disconnecting single PV circuits and is certified to IEC 60947-1 and IEC 60947-3 standards.
