Surge Protection

This 8-port Gigabit Ethernet surge protector is a professional lightning protection device designed for multi-channel network systems. It integrates 8-channel RJ45 interfaces, supporting high-speed Gigabit (10/100/1000Mbps) data transmission with ultra-low insertion loss. With a nominal discharge current (In) of 5kA and maximum surge current (Imax) of 10kA, it provides reliable surge protection for PoE network devices, such as IP cameras and network switches, while ensuring stable signal transmission. Its rugged metal housing and intelligent protection design make it ideal for centralized network surge protection in surveillance, industrial, and commercial scenarios.

The ZR-24V DC Signal Surge Protective Device (SPD) is a compact, DIN-rail mount surge arrester designed for 24V DC low-voltage signal and control circuits. With a nominal discharge current (In) of 5kA and maximum surge current (Imax) of 10kA, it provides reliable lightning and transient overvoltage protection while ensuring high-speed, low-loss signal transmission. Ideal for industrial control, security, and automation systems, it safeguards sensitive 24V DC equipment from surge damage.

This 2P single-phase AC Surge Protective Device (SPD, model ZHSPD-40) is a Class II (Type 2) surge arrester, designed for 220/385V AC power systems. It offers reliable protection against lightning-induced surges and grid switching overvoltages, with a nominal discharge current (In) of 20kA and maximum surge current (Imax) of 40kA. Featuring advanced chip manufacturing technology, a flame-retardant housing, and DIN-rail mounting, it is ideal for residential, commercial, and small industrial power distribution scenarios to safeguard electrical equipment from transient overvoltage damage.

This DIN-rail mount AC Surge Protective Device (SPD) is a Class II (Type 2) surge arrester, designed for three-phase and single-phase AC power systems (2P/4P options, 20KA–100KA surge current capacity). It provides robust lightning and switching overvoltage protection for industrial, commercial, and residential power distribution systems, featuring chip manufacturing technology, strong surge bearing capacity, and fire-retardant housing to ensure reliable operation and equipment safety.

This high-performance POE lightning and waterproof surge protector is professionally designed for outdoor monitoring and gigabit network systems. Equipped with standard gigabit network ports, it fully adapts to POE cameras and various network monitoring equipment, offering stable protection for monitoring signal transmission. Adopting a waterproof and durable structural design, it effectively resists harsh outdoor environments such as rain and humidity. The device features precise surge suppression technology, which can quickly divert lightning induced overvoltage and transient current, preventing network equipment from burnout and signal disorder caused by lightning strikes and electrical surges.
