is recommended for use with local level power distribution, appliances,
portable equipment, etc, where only smaller transient overvoltages may
occur, and not for primary supply lines, overhead lines and cable systems.
The AC7B is EN600- certified for Installation Category III
(600 V). It is recommended for use in distribution level and fixed
installations, as well as lesser installations, and not for primary
