LIGHTNING-SURGE PROT. type 1 (Citel, DS60VGPV-1000G/51)

Form

This SPD provides Type 1+2 protection for PV installations up to 1200 V DC, using VG technology (high-energy varistor + gas tube) for long service life, zero leakage current, and strong protection in common and differential modes.

  • nominal system voltage (Uocstc): 1000 V DC

  • maximum continuous operating voltage (Ucpv): 1200 V DC

  • voltage protection level (Up): 5.4 kV (+/–), 4.7 kV (+/PE or –/PE)

  • short-circuit withstand (Iscpv): 15 000 A

  • nominal discharge current (In): 20 kA (8/20 µs)

  • SPD type / class: type 1 + 2 (IEC 61643-31)

  • Imax: 40 kA per pole (8/20 µs)

  • Iimp: 12.5 kA per pole (10/350 µs)

  • number of poles: + / – / PE

  • dimensions: 90 × 90 × 70 mm

  • weight: 0.658 kg

Per piece.

Fit

  • installation location: PV string combiner / DC distribution enclosure

  • recommended back-up fuse / MCB: none required (internal thermal disconnector)

  • PV system compatibility: + / – / PE configuration (common and differential protection)

  • mounting type: 35 mm DIN rail

  • IP protection: IP20

  • max wire size: 6…35 mm² (screw terminals)

Function

This SPD protects 1000–1200 V DC PV strings from high-energy lightning currents and switching surges. VG technology combines a high-energy varistor with a specific gas tube to eliminate leakage current and extend service life. It provides coordinated protection in both common and differential modes and features a failsafe thermal disconnection system with mechanical indication and remote signalling via a changeover contact.
