Product Description
(BDS-C/2+1-320) (BDS-C/3+1-320) is a surge protector made of N-PE gas discharge gap, used for lightning protection of TT distribution systems in 220/380. It can be used as an equipotential connection during lightning strikes. Its design is in accordance with IEC-61643-1 and GB18802.1 (2002 edition) standards. The protector can be made with a remote signaling contact function. The remote signaling contact is a normally open contact. If one or more modules of the protector fail, the contact will close and send a fault signal. The remote signaling contact is set at AC36V, 1A.
