SPA108 Datasheet (Click here to open)

The SPA108 is a Type 2 photovoltaic surge arrester.

This complete device consists of a base part and pluggable modules. The SPA108 is recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 1-2 for equipotential bonding of positive and negative busbars of photovoltaic systems and elimination of transient overvoltages that originate during atmospheric discharges or switching processes.

• Maximum Continuous Operating Voltage – 1050V DC
• Short-circuit Withstand Capability – 100A
• Max. Discharge Current (8/20) – 40kA
• Nominal Discharge Current (8/20) – 15kA
• Voltage Protection Level at I_n – < 3.8kV

This surge protection device can be purchased as a unit on its own or with a metal or plastic enclosure.
