The JSPD series Class C Surge Protective Devices (SPDs) are high-performance modular solutions designed to protect low-voltage AC power systems from transient overvoltages caused by lightning strikes and switching surges. Compliant with IEC 61643-1 and GB 18802.1 standards, these SPDs are engineered for reliable equipotential bonding at LPZ0B/LPZ1/LPZ2/LPZ3 interfaces, making them ideal for residential, commercial, and industrial applications.

1kgThe 3 series C-class surge protector (SPD) is suitable for TN-S, TN-C-S, TT, IT and other power supply systems with AC 50/60Hz, 385V/380V and below. It can be used as an equipotential connection at the interface of LPZ1, LPZ2, and LPZ3 zones. Its design basis complies with IEC61643-1 and GB18802.1, and the shell design is installed on a 35mm electrical guide rail. This product has a built-in failure release device. When the surge protector fails due to overcurrent overheating and breakdown, the failure release device can automatically disconnect it from the power grid. At the same time, the visual alarm indicator module changes from green (normal) to red (faulty), and the module can be replaced under working voltage.

Product application and installation location
The 3 series of C-grade products are suitable for C-grade lightning protection and are used for equipotential connection during lightning strikes. They are installed at the junction of LPZOB area, LPZ1 area, and LPZ2 area. They are usually installed in residential distribution boxes, computer centers, telecommunications rooms, elevator control rooms, variable frequency equipment control rooms, hospital operating rooms, monitoring rooms, and distribution boxes in places with electronic medical equipment. SPDs should be installed in residential distribution boxes for dispersed small villas. Product design and ordering instructions: Users should clearly indicate the product series model and quantity when designing and ordering products. For example: 3 series LPFL-40/4P-385V, 8 units.
