Product Introduction TRSS-485 Surge protector protect n-earthed date (asymmetrical,suspended)cable that used for dual wire electronic measurement and control and the voltage shall not exceed 110V, frequency not more than 2MHz, to prevent date cable and related equipment from being damaged due to surging over-voltage caused by lighting or traveling ware. TRSS-485 two-stage circuit consists of gas discharging tube, piezore-sistance and clamping diode,with advantages of large discharging capacity,short clamping time and low protection level. Technical Parameter

 Installation To be mounted in the interface between LPZ1 to LPZ3.Can be mounted on 35mm rail of different standard switching box or distribution box.It does not need screws for connection with terminal.
