ZS-1I, ZS-1P are the surge arresters type 3 according to EN 61643-11 and IEC 61643-11 and IEC 61643-11 designed for installation into electrical installation systems, e.g.: cable ducts and flush-mounted sockets as an additional protection. These devices are suitable supplements of socket distribution which are protected by PI-k protector. The right function of ZS-1I type is indicated by green LED diode. When the indicator is dark, the device must be replaced or technically checked. ZS-1P contains an acoustic fault indicator (buzzer).
