Single-pole lightning and transient (switching-) surge voltage arrester for the protection of low-voltage electrical distribution systems by industrial, commercial and private use. Single-pole SPDs are used in 1-phase TN networks, where the N conductor does not have to be protected.
- Remote signalling contact: break contact
- Combined Arresters Class I+II+III (T1+T2+T3)
- Test standard: IEC 61643-11 / EN 61643-11
- Combined Arresters Class I+II+III (T1+T2+T3)
- No leakage currents, thus, allowing installation upstream of power meters
- Rare-gas-filled spark gap, hermetically sealed
- Applicable at the boundaries LPZ 0A - 1 and higher.
- 35 mm DIN rail (EN 60715)
- EAC certification
