DC Surge Protection Device 1000V 40ka SPD for Solar System

Product DescriptionApplicationThis T1+T2 DC spd surge protective device is applied low voltage standard IEC EN 61643-33 to protect against DC power line system and other equipment from over voltage and instantaneous over voltage damage. Widely used in photovoltaic comber box, power inverter, DC distribution cabinet etc. It has advantages of large discharge current, fast respond time, low residual voltage.The max. PV voltage up to UCPV ≤1500V dc. Features1. Prewired complete unit consisting of a base part and plug-in protection modules2. High discharge capacity due to heavy duty zinc oxide varistors3. High reliability due to 'temperature-controlled' SPD monitoring device4 .Din rail installation, easy to install.5. Inside over-current, over-heat, temperature control open circuit.6. Fast response time, low residual voltage.7. Window color indicates working condition, green means normal, red means fault.8. Class I II T1+2 protection degree. Installation positionThe cross-sectional area of ground wire should not be less than 4 mm2, and the length of total lead not more than 0.5m. 0.5MM The minimum distance from any earthed conductive surface at which the SPD can be installed is 8mm.  Connection of remote signalling alarm: the SPD is provided with remote signalling interfaces (NC, COM and NO, normally closed), applicable for remote centralized monitoring or alarm. After the connection, check if the module is fitted in. If so, NC and COM are closed; if not, repress the module.ModelLY1-C40PVSPD according to EN 61643-11 / IEC 61643-11Type 1+2 / class I+IIMax. continuous operating pv. voltage Uc1000V DC Nominal discharge current (8/20μs) In20kAMaximum discharge current (8/20μs) Imax40kAMaximum impulse current (10/350μs) Iimp6.25 kAImpulse current totally (10/350μs) Iimp12.5kAVoltage protection level Up3.6 kV Follow current extinguishing capability [N-PE] Ifi100ArmsResponse time tA25ns (L-N)Matched fuse or circuit breaker32AOperating state / fault indicationGreen ok / Red defectCross-sectional area (min.)1.5 mm2 solid /flexibleCross-sectional area (max.)35 mm2 stranded / 25 mm2 flexibleFor mounting on35 mm DIN rail acc. to EN 60715Switching capacityAC:250V/0.5A DC:250V/0.1A,125V/0.2A,75V/0.5ARemote signalling alarming modeNormal: closed; Failure: open-circuit
