BVT KKS APD 36 Surge Arrester
Brand: DEHN, IncEnergy-coordinated combined lightning current and surge arrester for protecting voltage measuring circuits (yellow colour).
Plug-in remote signalling contact (break contact) indicates overload (thermal monitoring of the discharge paths.
Installation into steel-sheet enclosure recommended.
A low impulse sparkover voltage is achieved by capacitive control.
