In an electrical systems, Solar DC SPDs are usually installed in tap-off configuration (in parallel) between the live conductors and the earth. The operating principle of Solar DC SPD can be similar to that of a circuit breaker.
In normal use (no overvoltage): the Solar DC SPD is similar to an open circuit breaker.
When there is an overvoltage: the Solar DC SPD becomes active and discharges the lightning current to earth. It can be likened to the closing of a circuit breaker which would short-circuit the electrical network with the earth via the equipotential earthing system and the exposed conductive parts for a very brief instant, limited to the duration of the overvoltage.
For the user, the operation of the Solar DC SPD is totally transparent as it only lasts a tiny fraction of a second.
When the overvoltage has been discharged, the Solar DC SPD automatically returns to its normal state (circuit breaker open).

Professional China quality AC Surge Protection Manufacturers and Suppliers.
YL1-C40 AC Surge protection device is suitably used in the TT, TN-S, TN-C, IT, TN-C-S and etc power supply system of AC 50/60Hz,<380V, installation om the joint of LPZ1 or LPZ2 and LPZ3, it is designed according to IEC61643-1, GB18802.1, it adopts 35mm standard rail, there is a failure release mounted in the module of surge protection device. When the SPD fails in breakdown for over-hart and over-current, the failure release will help electric equipment separate from the power supply system and give the indication signal, green means normal, red means abnormal, it also could be replaced for the module when has operating voltage.
