Product characteristics
Protection for consumer units- For residential and small commercial installations
- With plug-in modules and status indicators:
- Green: SPD operational
- Red: plug-in module need to be replaced
- For installations with low risk level (in urban areas, underground power supplies, etc.)
- In: 10 kA/pole - Uc: 275 V~
- Earthing systems: TT, TNS
- Cat. No. 0 039 51: SPD with Y connection (both incoming and outgoing terminals at the top of the SPD) providing better protection against overvoltages
- 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 : 3P+N
- Neutral position : Left
- Integrated protection : Isc ? 6 kA
- Number of modules : 6
General characteristics
Class II (T2) low voltage SPDs with integrated protection- SPDs with integrated protection against overload currents and short-circuit currents
- SPDs compliant with EN/IEC 61643-11 standards
- For 230/400 VA power networks (50/60 Hz)
