Schneider Electric has announced the release of IEC extensions for its NSX and Acti 9 ranges to meet the special high-performance requirements of photovoltaic (PV) systems.
"A PV solar installation generates variable DC output from multiple sources - solar modules arranged in arrays - which requires special disconnects to isolate components. What's more, its short-circuit current is limited, so overcurrent protective devices need to operate at low fault currents. Protection and control devices to operate in a PV installation need to be designed to meet these and other specific requirements of these highly-demanding systems," said Matthieu Guillot, PV Applications Engineer, Schneider Electric.
