PIVM12,5-275 IT DS/2+1 Vseries
Article number: 16 164- Lightning impulse current and surge arresters type T1+T2 ensure the equipotential bonding, eliminate the effects of lightning current and reduce switching, induced and residual overvoltage in single-phase IT power supply systems.
- The products consist of varistors with big discharge ability with gas discharge tube, which ensures zero leakage current in the PE conductor.
- Installed at the boundaries of zones LPZ 0 – LPZ 1 and higher closest to where the overhead line enters the building.
- Suitable for objects with considerable levels of protection LPL III and LPL IV.
- M specifies a type of construction with removable module.
- DS indication specifies a version with remote monitoring.
- Other voltage levels can be produced on request.
