| Keywords: Level 1 power lightning protection box, Level I box type power surge protector, Main power lightning protection box, Level B power lightning protection box |
| The PB series box type Class I power surge protector is designed according to IEC and GB standards and has high lightning current discharge capability. The maximum impulse current per line can reach 25kA (10/350 μ s), which can prevent various surges including direct lightning strikes. It is used as the first level surge protection for equipment systems in areas with high lightning risk. The lightning protection box is equipped with power indicators, protection indicators, lightning strike counters, lightning protection circuit breakers, etc., and can be fixedly installed on the wall. |
