Outline and Mounting Dimensions
ND10-B Power Surge Protector
Conforming to GB18802.1 or IEC61643-1, the ND10-B series surge protective device, hereinafter referred to as SPD, is suitable for use in the power supply system with the rated voltage below AC 380V and the frequency of 50 or 60 Hz. It is used for protection against surge resulting from direct or indirect lightning or other transient voltages. SPD offers common mode protection and differential mode protection.

Our surge protector is built with a disconnector. When it fails due to overheat or breakdown, the disconnector can automatically disconnect the SPD from the power grid and issue an indication signal. When the surge protector works normally, the visual window displays white; when it fails, the window shows red.
Installation
1. This SPD is installed in the LPZOB or the junction of LPZ1 area and LP22 area with a 35mm standard rail. Multi-strand copper wire with the cross-section of 2.5 to 35 mm2 is used for connection.
2. Each pole of SPD must be set with protective device, such as a fuse or miniature circuit breaker.
ND15-B Surge Protector
The ND15 series surge protector is used for protection against surge caused by direct or indirect lightning or other transient voltages in the power supply systems, like IT, TT, TN-C, TN-S, and TN-CS, with the frequency of AC 50 or 60 Hz and the rated voltage of 380V.
This surge protection device is in line with GB18802.1 or IEC61643-1. According to the IEC 61643-1: 1998-02, it belongs to a Class B surge protector, suitable for use in high lightning-risk areas.
