PIIIM-275/4+0 Vseries
Article number: 27 052- Surge arresters type T2 ensure the equipotential bonding and reduce switching, induced and residual overvoltage in LV power supply systems.
- The products consist of varistors with big discharge ability.
- Configurations 1+1 and 3+1 are additionally combined with a gas discharge tube which ensures zero leakage current through the PE conductor.
- Installed on the interface of LPZ 1 – LPZ 2 into subsidiary switchboards and control boxes.
- M indication specifies a type of construction with removable module.
- DS indication specifies a version with remote monitoring.
- Other voltage levels can be produced on request.
