Overvoltage surge protection device (SPD), ION-V-150/50 3+0

The surge protection device (SPD) is designed to protect electrical equipment in low-voltage power distribution systems with a frequency of 50-60 Hz and rated voltage of 120/160 V from the effects of impulse lightning surges, as well as switching overvoltages, the sources of which are switching in the circuits of inductive and capacitive loads, short circuits in distribution electrical networks of high and low voltage. The surge suppressors belong to test classes II and III according to GOST IEC 61643-11 and can be installed in switchboards or in special separate panels near the switchboard or directly near the protected equipment in order to ensure its protection in accordance with its category of overvoltage (I - IV) and the required rated impulse voltage Uw according to GOST R 50571.4.44 and GOST R 50571.5.53
