Product Description
Class C Power Surge Protectors SPD
LYD3 series surge protective device is suitable used in the IT, TT, TN-C, TN-S, TN-C-S and power supply system of AC 50/60Hz, rated voltage up to 380V, to protect from direct and indirect lightning impulse and other transient over voltage. As per the conditions of IEC61643-1:1998-02 ST standard, Class 2 surge protective device, it is category B surge protective device. SPD is incompliance with IEC 61643-1 standards.
Operation Elements
- Single pole structure, single pole or three poles combined SPD available.
- SPD has built-in disconnector, when SPD is invalid due to overheating or breakdown, the disconnector can automatically separated SPD from network, meanwhile send an indication signal.
- The visible window show white color in normal service, if to be separated from network, it will show red color, it can adopt Kelvin wiring mode.
- Large current carry capacity, fast response time, low residual voltage.
Installation:
- Category B surge protective device (SPD) used in the connection between equal potential electrodes while thunder occur.
- To be mounted between LPZ0A or LPZ0B zone and LPZ1 zone, adopts 35mm standard mounting rail. The cross sectional area of multi-standard soft copper conductor 2.5 to 35mm2.
- Generally to be installed in low voltage main incoming distribution panel, overhead incoming.
- As required, the user can assemble single pole or three poles surge protective device freely.
- Generally to be installed in low voltage main incoming distribution panel, earthing wire shall be dual color multi-stand soft copper conductor more than 16 mm2.
