7. Class B+C Protection Set
It shall be comprised of the combination of Spark-Gap technology and varistor technology. The set providing protection
of 100 kA in total - 50 kA per phase and 100-125 kA between Neutral/Ground - shall be installed onto main secondary
panels in the building, which are to be used for electric supply to the uninterruptible power supply. The products shall have
the properties given below:
—It shall feature Class B+C (Type 1+2) and 3+NPE (3 phase, neutral-ground) connections. (This set shall be considered 1
piece)

8. Class B+C Protection with Power Varistor Connected between Three Phase+Neutral/Ground (Combined Lightning and

Overvoltage Discharge Assembly)
The switch automatic fuses and residual current relays having no appropriate amperage, which are available in distribution
panels of uninterruptible power supplies feeding the camera system, shall be replaced by those having appropriate
amperage, and B+C type protection products shall be installed in the feeder inlet before the uninterruptible power
supply. The protection products to be used shall have the properties given below:
—It shall feature Class B+C (Type 1+2) and 3+NPE (3 phase, neutral-ground) connections. (This set shall be considered 1
piece)
