LIGHTNING-SURGE PROT. type3 (Dehn953205) 2P/3kA, mod+contact

Form

This SPD provides Type 3 protection for 230 V AC installations, using a two-pole modular design with a plug-in protection module and a varistor/spark-gap combination for high discharge capacity. It includes fault indication and a floating changeover contact for remote signaling.

  • nominal voltage (UN): 230 V AC

  • maximum continuous operating voltage (Uc): 255 V AC (a.c.) / 255 V (d.c.)

  • voltage protection level (Up): ≤ 1.25 kV (L–N), ≤ 1.50 kV (L/N–PE)

  • short-circuit withstand (ISCCR): 6 kA

  • nominal discharge current (In): 3 kA (8/20 µs)

  • SPD type / class: type 3 / class III (IEC 61643-11)

  • total discharge current (Itotal): 5 kA (8/20 µs)

  • number of poles: 2 (L + N/PE)

  • dimensions: 1 module (DIN 43880)

  • weight: 84 g

Per piece.

Fit

  • installation location: main AC distribution board / sub-distribution

  • recommended back-up fuse / MCB: max. 25 A gG or B-curve 25 A

  • AC system compatibility: 230 V AC (L–N / L/N–PE)

  • mounting type: 35 mm DIN rail

  • IP protection: IP20

  • max wire size: 0.5…4 mm² (solid) / 0.5…2.5 mm² (flexible)

Function

The surge protective device (SPD) protects AC terminal circuits and connected loads from transient overvoltages caused by switching operations or indirect lightning effects.
Using a varistor and spark-gap combination, it limits surge energy in L–N and L/N–PE modes while maintaining fast response characteristics.
It includes a floating changeover contact for remote signaling and provides Type 3 protection suitable for terminal equipment.
