Solectria Renewables LLC has introduced its ARCCOM disconnecting string combiner with integrated arc fault detection and interruption. It is compatible with all of Solectria's three-phase central inverters.
The ARCCOM is compliant with NEC 2014 arc fault and rapid shutdown requirements and contains a contactor disconnect, lockable switch and string level arc fault protection, allowing it to detect and interrupt a series arc. Solectria says the product is designed for extreme conditions and temperature ranges.
The ARCCOM also features standard oversized compression lugs that allow for long home run conductors. Additional options include: a surge arrestor, optional AC power supply and stud connector plates for those installers that prefer crimped connectors.
