Panel Switch: PV Surge Protector T1+T2 B+C 3P 3M 20/40kA 4.75kV 1000V DC – iluve OP-PV20 B+C T1/T2 (v.1)

The iluve OP-PV20 B+C T1/T2 is a professional protection switch (type 1+2) designed to protect photovoltaic installations on the DC side. The device combines protection functions against surges (T1) and transient overvoltages (T2) in a single enclosure, ensuring absolute safety for the photovoltaic system against atmospheric discharges and switching surges.

Application

The OP-PV20 B+C T1/T2 model is intended for use on the DC side of photovoltaic installations with a nominal voltage up to 1000 V DC. It is suitable for both residential systems and large industrial installations. Thanks to the use of three replaceable modules in a Y-configuration, it provides full protection of photovoltaic arrays from induced and direct transient surges.
