Product introduction YTTS1-C40 series surge protection device is suitable for TN-S, TN-C-S, TT, IT etc, power supply system of AC 50/60Hz,<380V, installed on the joint of LPZ1 or LPZ2 and LPZ3. It's designed according to IEC61643-1, GB18802.1, it adopts 35mm standard rail, there is a failure release mounted on the module of surge protection device, When the SPD fails in breakdown for over heat and over-current, the failure release will help electric equipments separate from the power supply system and give the indication signal, green means normal, red means abnormal, it also could be replaced for the module when has operating voltage. Product features 1.Inside over-current and over-heat protection, temperature control open circuit. 2.Module design, convenient installation, could be replaced. 3.Time of response <25n 4.The color of visible window shows operating status, green means normal, red means abnormal Product specifications Product Model YTTS1-C40 Pole 1P+N 2P Rated Frequency One port SPD Category Compact type Test Category Cla 2test Maximum Continuous Operating Voltage Uc 275VAC 275VAC Voltage Protection Level Up(8/20s) 1.5kV 1.5kV Nominal Discharge Current ln(8/20s) 20kA Maximum Discharge Current lmax(8/20s) 40kA Response Time tA 25ns Size 18x90x72 36x90x72 Failure Indication Green: Normal Red: Failure Sectional Area Of Wires 6~25mm2 Installation Method 35mm standard rail Working Environment Temperature -40 ~+85 Sheathing Material Plastic Protection Level IP20 Executive Standard IEC 61643-11
