Lighting Current Arresters

FLP-B+C MAXI VS

SPD type 1 – combined arrester type 1 and 2 Dimension drawing Basic circuit diagram

Surge protector devices (SPD) of class B+C serve for protection of low-voltage (230/400 V AC) networks and connected appliances against surge voltages due to direct - and indirect lightning strikes. The FLP-B+C MAXI VS SPD is built in a single block. Module offers a combination of heavy duty gas discharge tube (GDT) rated at 25 kA (10/350 μsec pulse) with high energy varistors block. This module guarantee no follow-on current, very low leakage current (μA range) and very low residual voltage. The form a part of the protection of buildings and their accessories in the concept of zone lightning protection at the boundary of the LPZ 0 and LPZ 1 (or higher) zones. § reliable arrester disconnection during overload or damaging of the protective module by thermal and dynamical varistor disconnection § optical fault indication – changing color of the signaling flag from green to red

§ low voltage Up

§ housing material according to UL 94 V0
