Leutron - PowerPro BCD TNC/TNS/TT

Combined modular multi-pole arrester for lightning (LEMP) and transient (switching-) surge voltage protection (SEMP) of low-voltage electrical distribution systems for industrial, commercial and private use. Suitable for the installation at the 0A-2 boundaries according to the Lightning Protection Zone Concept of IEC 61312.

• ready for use, modular all-in-one protection unit
• hermetically sealed, built-in rare-gas-filled isolated spark gaps
• no blow-out vents, i.e. not requiring any safety distances for installation
• up to 100 kA discharge capacity (10/350 µs)
• high quenching capacity of follow-on short circuit currents
• high insulation resistance Riso > 10 GΩ
• protection level from < 0.75 kV up to 1.0 kV
• V-wiring over multi-functional terminals possible
• no leakage-currents, i.e. allowing installation upstream of power meters
• ptional remote contact (FM)
• max. operational availability
• high TOV resistance
• functions independently of atmspheric air pressure and ambient humidity
