Type 2 surge arrester – ‘Y’ connection
Type 1+2 surge arrester – ‘Y’ connection
Surge arresters for use in photovoltaic systems with ‘Y’ connection. Protects both poles.
Use on systems up to 750 volts, 1020 volts and 1500 volts.
- Pluggable module
- Visual fault signalling
- Module locking
- Remote fault signalling
Ideal for use with photovoltaic systems where the separating spark-over distance is without a Lightning Protection system.
BS:EN 62305 (lightning protection) and EN 61643-11 (surge protection devices).
Spare modules are available
|Spare Module (750V DC)|
|Spare Module (1020V DC)|
|Spare Module (1500V DC)|
Replace when fault indication indicator turns from green to red
