HLSA12,5-275/3+1 S IT

Lightning and surge arresters T1+T2 for IT systems

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 and three-phase IT power supply systems.
The products consist of varistors with big discharge ability in the combination with gas discharge tube they ensure 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 i.e. in the main distribution boards.
Suitable for objects with considerable levels of protection LPL III and LPL IV.
S indication specifies a version with remote monitoring.
