Product Description
Product Description
Application
This T2 spd surge protective device is applied low voltage standard IEC EN 61643-11 to protect against AC 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 Uc ≤275V .Features
1. Prewired complete unit consisting of a base part and plug-in protection modules
2. High discharge capacity due to heavy duty zinc oxide varistors
3. High reliability due to 'temperature-controlled' SPD monitoring device
2. High discharge capacity due to heavy duty zinc oxide varistors
3. High reliability due to 'temperature-controlled' SPD monitoring device
4 .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.
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 II T2 protection degree.
Installation position
The 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.
