Product Description

Product Description

 DC Surge Protective Device Protection  SJKS1 safety 

   The SJKS1 series surge protective device (SPD) is suitable for AC 50/60Hz, 380V and below power supply systems such as TN-S, TN-C-S, TT, and IT. It can serve as an equipotential bonding device at the boundaries between LPZ1, LPZ2, and LPZ3 zones. The design complies with GB18802.1 and IEC61643-1 standards. The housing is designed for installation on a 35mm rail. The product features a built-in failure disconnection mechanism, which automatically disconnects the SPD from the power grid in case of overcurrent, overheating, or breakdown failure. At the same time, the visual alarm indicator module changes from green (normal) to red (fault). The SPD module can be replaced online.

Product Application and Installation Location

        Suitable for C-level lightning protection, the SJKS1 series surge protective device complies with GB18802.1-2002 and is used for equipotential bonding in motor applications. It is installed at the boundaries between LPZ1, LPZ2, and LPZ3 zones, typically in floor distribution boxes, computer centers, telecommunication rooms, elevator control rooms, variable frequency equipment control rooms, hospital operating rooms, intensive care units, and distribution boxes in locations equipped with electronic medical devices. For decentralized small villas, the SPD should be installed in the household distribution box.
