SURGE ARRESTER type 1+2, 1P+N 350V, modular, remote transfer

Form

This SPD provides combined type 1 and type 2 protection for low-voltage distribution networks, using a removable cartridge design for easy maintenance and high-energy handling.

  • nominal system voltage (Ue): 230 V AC (+/–10 %)

  • maximum continuous operating voltage (Uc): 350 V AC (L/N and N/PE)

  • voltage protection level (Up): < 1.5 kV (L/N and N/PE)

  • short-circuit withstand (Isccr): 25 kA

  • nominal discharge current (In): differential mode 25 kA, common mode 100 kA

  • response time: ≤ 25 ns

  • SPD type / class: type 1 + 2 (IEC 61643-11)

  • Iimp: differential mode 25 kA (L/N), common mode 100 kA (N/PE)

  • number of poles: 1P + N

  • dimensions: 90 × 71.6 × 70 mm

  • weight: 0.77 kg

includes

  • 1 × SPD module

  • 1 × instruction manual

Per piece.

Fit

  • installation location: main distribution board / sub-distribution

  • recommended back-up fuse / MCB: gG 315 A or NSX/NSXm breakers up to Isc = 25 kA

  • AC system compatibility: TT / TN-S

  • mounting type: 35 mm DIN rail

  • max wire size: 2.5 to 35 mm² (cage terminals)





Function

This SPD protects electrical installations against transient overvoltages caused by lightning or switching operations. Its hybrid spark-gap and MOV design allows it to handle very high impulse currents in both common and differential modes. The removable cartridge allows quick replacement, while mechanical and remote indication (1 C/O contact) provides immediate visibility of operational status and end-of-life conditions.
