Two-pole ultrasonic protection devices of combined type of test class I+II. They are used in low-voltage electrical networks at the boundary of 0A(V) - 1 lightning protection zones (in accordance with GOST R IEC 62305-1 and SO-153-34.21.122).
Uo = 230 B AC. Iimp(10/350)= 25 kA.
In the protection circuit varistors and gas-filled arresters are connected in series, which excludes the presence of leakage current. They are intended for protection of AC power circuits with TN-S type earthing system at cable or air power supply input.
