ONCCY Electrical’s photovoltaic rapid shutdown Devices are used in European rooftop photovoltaic projects to protect the safety of PV panls.
ONCCY ERS series rapid shutdown switch(RSD) is designed for pv array system. By installing the ERS firefighter safety switch, firefighters can remotely turn off the AC power to disconnect the DC circuit before extinguishing the fire. The quick-shutoff switch will automatically disconnect the internal DC isolation switch after collecting the signal from the power grid.
