CITEL DPVN1-6CVGS – Type 1+2 Surge Protection Device for Photovoltaic Systems
Iimp 6.25 kA per pole | Itotal 12.5 kA | VG + CTC Technology | Compact DC SPD
The CITEL DPVN1-6CVGS is a compact Type 1+2 SPD designed to protect DC photovoltaic systems against lightning-induced surges and transient overvoltages. With a total impulse current rating of 12.5 kA (10/350 µs) and VG technology (varistor + gas discharge tube) enhanced by CTC (Central Thermal Control), it delivers effective, stable protection without follow current.
This SPD is ideal for space-constrained PV systems requiring robust surge handling at the combiner box, string level, or inverter input. It ensures safe operation of solar arrays while simplifying maintenance and system integration.
