HSA-600/3+1 S IT
Article number: 27 650- Surge arresters type T2 ensure the equipotential bonding and reduce switching, induced and residual overvoltage in single-phase and three-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 1 – LPZ 2 into subsiduary switchboards and control panels.
- S indication specifies a version with remote monitoring.
