Product Description

Product Description

JCHKO SJKS1  Series 4p High-Performance Surge Protection Device for Safety

    SJKS1 series surge protective devices (SPDs) are suitable for AC 50/60Hz, 380V and below TN-S, TN-C-S, TT, IT and other power supply systems. They can be used as equipotential bonding at the interface of LPZ1, LPZ2 and LPZ3 zones. Their design complies with GB18802.1 and IEC61643-1 standards, with an enclosure designed for installation on 35mm DIN rail.

    The product is equipped with a built-in failure detachment device. When the surge protective device fails due to overcurrent, overheating or breakdown, the failure detachment device automatically disconnects it from the power grid. Meanwhile, the visual alarm indicator module changes from green (normal) to red (fault). Surge protective device modules can be replaced online.

Product Application and Installation Location

     The SJKS1 series products are used for Class B lightning protection and equipotential bonding for motors. They are installed at the interface between LPZOA/LPZOB zones and LPZ1 zone. SJKS1-100 and SJKS1-80 are typically installed at the low-voltage main distribution cabinet where cables enter through buried pipes.
