Power Engineering
Class I+II+III (T1+T2+T3) Combined Arresters
PowerPro BCD, 2-pole
• All-in-one modular protection unit, ready for connection
• Rare-gas-filled spark gap, hermetically sealed
• Discharge capacity up to 100 kA (10/350 µs)
• High quenching of follow-on short-circuit currents
• High insulation resistance
• Maximum operational availability
• High TOV resistance
• V-wiring with multi-functional terminals
• Protection level from < 0.75 kV up to 1.0 kV
• No blow-out vents, thus, not requiring any safety
clearance to other installations
• No leakage currents, thus, allowing installation
upstream of power meters
• Optional remote signalling contact (FM) requiring no
additional space
• Operates independently of atmospheric air pressure
and ambient humidity
Two-pole combined arrester for the protection of low-voltage
consumers’ installations in industry, business and residential
areas against transient surges caused by lightning (LEMP) or
switching actions in the network (SEMP).
The TT system version discharges impulse currents between L
and N. Between N and PE a Leutron summation current spark
gap SumPro with 100 kA (10/350µs) will be applied which corresponds
to the highest lightning protection class I according
to VDE 0185-305 (IEC DIN EN 62305).
The arresters can be installed at the transition 0 A to 2 according
to the lightning protection zones concept.
There are special models available with an integrated control
indication via LED for the conductor and the arrester function.
All technical data and dimensions correspond to those
of the standard version.
