DC surge protector 1200V 40kA T1+T2 DTE DSPD-DC1200-40 3P
The DSPD-DC1200-40 3P class T1+T2 (B+C) surge arrester is used to protect photovoltaic installations against induced voltages, switching voltages and voltages caused by atmospheric factors.
The DSPD-DC1200-40 3P class T1+T2 (B+C) surge arrester is used to protect photovoltaic installations against induced voltages, switching voltages and voltages caused by atmospheric factors.
They are equipped with a visual operation indicator (green – protection, red – no protection).
The APV arrester is constructed using a special high-flow varistor and a gas spark gap.
The limiters have features that make them easier to install and operate.
