EHD series products are DC load disconnectors. They can ensure the disconnection and connection of DC circuits under load, as well as safety isolation. They are mainly used in the field of photovoltaic systems. The rated voltage can reach 1500VDC and the maximum current can reach 630A.They has two installation methods,Directly operate the handle in the cabinet (DB) and Outside handle (DC).
ONCCY offers a range of load break switches for PV Solar System. Overrated neutral, high short-circuit withstand but also motorised: the devices adapt to all types of cut-off requirements. They can also be adapted to different applications such as earthing, tropical zones or remote control.
