LIGHTNING-SURGE PROT. type 1 (Dehn920324) 20Ka 24V

Form

This SPD provides coordinated lightning and surge protection for four signal lines sharing a common reference potential, with DEHN LifeCheck monitoring and pluggable base compatibility.

  • nominal system voltage (Un): 24 V

  • maximum continuous operating voltage (Uc): 33 V DC / 23.3 V AC

  • voltage protection level (Up): ≤ 102 V (line-line D1), ≤ 66 V (line-PG D1), ≤ 90 V (line-line C3), ≤ 45 V (line-PG C3)

  • short-circuit withstand (isccr): equal to nominal current IL = 0.75 A

  • nominal discharge current (In): 20 kA total (C2), 10 kA per line

  • response time: not specified (C2/C3 class SPD)

  • Spd type / class: class 1 (IEC/EN 61643-21)

  • Imax / iimp: 10 kA total (D1), 2.5 kA per line (D1)

  • number of poles: 4 single lines + PG reference path

  • weight: 38 g


Per piece.

Fit

  • installation location: pluggable into DEHN BXT BAS / BSP BAS 4 base

  • recommended back-up fuse / MCB: not applicable (signal SPD, IL = 0.75 A)

  • Ac system compatibility (earthing): earthing through BXT BAS / BSP BAS 4 base

  • mounting type: DIN-rail base (BXT BAS) with pluggable module

  • IP20 (plugged-in)

Function

This SPD module protects four single signal lines from lightning currents and transient overvoltages. It combines D1, C2 and C3 test class performance, providing both common-mode and differential-mode protection. LifeCheck monitoring allows non-contact thermal and electrical overload detection via DEHNrecord readers. It is suitable for industrial signal interfaces, unbalanced communication lines and installations up to lightning protection zone boundaries 0A–2.
