PP BCD TNC 25/75/FM
Article Nr. : 373992
The installation place of the PowerPro BCD is the main distribution board upstream or downstream of the power meter. According to the lightning protection zones concept in IEC DIN EN 62305 part 1-4 (VDE 0185-305-1-4), it can universally be installed at the transition 0A to 2. Combined three-pole arrester for 3-phase TN-C systems.
- Remote signalling contact: break contact
- Combined Arresters Class I+II+III (T1+T2+T3)
- Test standard: IEC 61643-11 / EN 61643-11
- No leakage currents, thus, allowing installation upstream of power meters
- Rare-gas-filled spark gap, hermetically sealed
- High quenching of follow-on short-circuit currents
- High insulation resistance Risol: ? 10 G?
- High TOV resistance
- EAC certification
