Signal and instrumentation protection

September 2014 Electrical Power & Protection

Saltek’s FLP-B+C MAXI VS/1+1 is a Class 1 and Class 2 combined lightning current arrester designed to protect LV single-phase TT (TNS, TNCS) networks against surge voltages due to direct or indirect lightning strikes. The modular two-pole lightning current arrester is a combination of heavy duty gas discharge tubes (GDT) rated at 25 kA (10/350 sec pulse) with a high energy varistor.

This proven technology guarantees no follow-on current, no leakage current and low residual voltage. The replaceable module has a visual fault indicator which changes to red when faulty, immediately informing the user of the operating state of the surge arrester. The lightning current arresters are used at the boundary of LPZ 0 and LPZ 1 or higher.

With a 100 ns response time, the module has overcurrent protection, mounts on a DIN rail, meets IP20 protection requirements and complies with the EN 61643-11 standard.
