Type 1 AC Surge Protectors

Type 1 surge protectors  are designed to be installed where a direct lightning strike risk is high, especially when the building is equipped with external lightning protection system  (LPS or lightning rod ). In  this situation, EN 61643-11 and IEC 61643-11 standards require the Class I test to be applied to surge protectors : this test is characterized by the injection of 10/350 μs impulse current in order to simulate the direct lightning strike consequence. Therefore these Type 1 AC surge protectors must be especially powerful to conduct this high energy impulse current.
