Type 2 Surge Protection Device (SPD) Surge Arrester
- Double Pole
- Can be retrofitted into exisiting consumer units
- NHSPD4621T2 2 conductor system; L, N / P
Type 2 Surge Arresters provide protection against overvoltage originating from switching and the secondary effects of lightning strikes. These devices will discharge current having an 8/20μs waveform and provide a low voltage protection level of ≤1.5kV (Up) for sensitive electronic equipment exceeding the requirements for category II equipment identified within table 44.3(BS7671).Surge and lightning arresters have a lifespan directly related to the number and magnitude of their operations. All Wylex devices provide visual life status indication. The plug in unit must be removed during installation insulation resistance testing.
