LIGHTNING-SURGE PROTECTION type 1 (Dehn920249) 20Ka 180V
Form
This SPD module provides coordinated lightning and surge protection for one signal pair, with automatic voltage adaptation (actiVsense) and RFID LifeCheck monitoring.

short-circuit withstand (isccr): equal to nominal current IL = 100 mA
nominal discharge current (In): 20 kA total (C2), 10 kA per line
response time: not explicitly stated (signal SPD, C2/C3 tested)
spd type / class: class M (IEC/EN 61643-21)
imax / iimp: 9 kA total (D1), 2.5 kA per line
number of poles: protection for 1 signal pair (2 wires + PG path)
weight: 23 g
Per piece.
Fit
installation location: mounted on DEHN BXT BAS / BSP BAS 4 base part
Ac system compatibility (earthing): earthing via BXT BAS / BSP BAS 4 base
mounting type: pluggable module into base (DIN-rail base)
indoor IP20 (plugged-in)
Function
This SPD module protects one signal pair against lightning currents and surge voltages. It automatically detects the operating voltage of the signal line and dynamically adjusts its protection level (actiVsense technology). The device combines D1, C2 and C3 test class performance, with both common-mode and differential-mode protection. The integrated LifeCheck system enables condition monitoring via RFID, allowing predictive maintenance.
