C+D Class

D+C arrester or 2+3 arrester provides 10 kA to 20 kA withstand voltage tolerance, with open contact outputs for connection to PLC as a single bridge and three bridges.

What is a Class C+D arrester?

These arresters are for protection against switching, which act as secondary protection against overvoltage and eliminate the leakage voltage from class B arresters and also transfer the voltages caused by switching on the power grid to ground.

The class C surge arrester is designed to be the interface between the conductor of the electrical system and the ground and reduce the amount of overvoltage in the electrical device. The class C surge arrester is single-pole and is used to protect electrical equipment during voltage changes caused by lightning.
