40KA Three Phase AC Sine Wave Tracking Mains Surge Arrester.


The BFR-40KA-3PNE features both Threshold Clamping Technology and Sine Wave Tracking Technology. The Threshold Clamping Technology clamps the surge once the threshold rating is reached. While, Sine Wave Tracking Technology is active surge protection and suppresses high-frequency low energy ring wave transients, RFI, EMI and EMC (Electromagnetic Compatibility) interference. The combination of both technologies in one surge arrester delivers unparalleled protection against lightning and load-shedding.
