- Class II (T2) low voltage SPDs – Protection against transient overvoltagess for 230/400 V~ power networks (50/60 Hz). SPDs compliant with EN/IEC 61643 – 11 standards – Recommended for distribution boards
- T2 SPDs – SPDs with plug-in modules and status indicators : – Green : SPD operational – Orange : plug-in modules to be replacedT2 – Imax 40 kA/pole – SPDs recommended for power installations – Up : 1.7 kV – In = 20 kA/pole – Uc : 320 V~ – Earthing systems : TT, TNC, TNS – Recommended MCB : DX³ 25 A – C curve – 1P+N and 3P+N : L – N and N – PE protection modes (common and differential modes) , the N pole being protected by encapsulated spark gaps. Also called 1+1 and 3+1 – Number of poles : 1P+N – Neutral position : Left – Remote status monitoring (FS contact) : No – Number of modules : 2
