BVT KKS APD 36 Surge Arrester

Brand: DEHN, Inc

Energy-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.
