10 - 20KA Double phase surge protection device for installation in
Surge Protection for Solar Photovoltaic (PV) System
The OBV6 series Surge Protection are designed to protect against
lightning surge voltages in photovoltaic power supply networks.
These units must be installed in parallel on the DC networks to be
protected and provide common and differential modes protection. The
OBV6-B+C40 series is available for the main operating voltages in
photovoltaic: 1000 Vdc.
The use of OBV6-B+C40 series Surge Protection is recommended at
both ends of the DC power supply line (solar panel side and
inverter/converter side), especially if the line routing is
external and long. The electrical diagram of the OBV6-B+C40 series
is based on high energy MOVs equipped with specific thermal
disconnectors and related failure indicators. The OBV6B+C40 series
is made with plug-in modules to allow a fast and easy maintenance
in case of failure (disconnection from the DC network).

1. You must cut off the power supply before installation, live line
work is strictly prohibited.
2. In protecting front line fuse or automatic circuit breaker.
3. Protector for the parallel installation, Kevin connection is
recommended (for Kevin wiring convenience, operates two terminals
on the module, which is a straight up. Kevin v-like connection is a
connection. A contact point and the two lines in parallel, one
into, a calculated). Connector requires solid and reliable, and
short, thick and straight.
4. Protector in use during the fault display window should
periodically verify and view state when red fault display window or
remote Terminal outputs alarm signals, the protector fails, should
be repaired or replaced in a timely manner.
5. When installed according to the installation diagram shows the
connection, where l (L1, L2, L3) for the line, n is neutral, PE
ground wire, do not mistake. After the installation is complete,
check that the protection unit is plug in place, close the
automatic circuit breaker (fuse) switch, check the working status
