SURGE ARRESTER TYPE 2
PHOTOVOLTAIC PROTECTION
a surge arrester type 2 photovoltaic surge arrester, consisting of a base part and pluggable modules
The WSP-T2PV2/40/1000 is a surge arrester type 2, according to BS EN 61643-11. photovoltaic surge arrester. This complete device consists of a base part and pluggable modules. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 1-2 (according to IEC 1312-1 and BS EN 62305) for equipotential bonding of positive and negative busbars of photovoltaic systems and elimination of transient overvoltages that originate during atmospheric discharges or switching processes.
The failure indication of these disconnectors is partly visual (discoloration of the signal field) and partly remote monitoring by potential free switching contacts.
