Surge Protection Device

Keeping your grid reliable has never been more important. With the power usage patterns shifting dramatically in these challenging times, power operators need to do make everything they can to avoid outages.

Designed with a combined Type 1+Type 2 structure, the SPD range offers impulse current up to 25kA and maximum discharge capacity up to 80kA, ensuring reliable protection against lightning and transient surges. Supporting system voltages up to AC1000V and DC1500V, it features a pluggable modular design with thermal disconnection, fault indication, and remote signaling for safe and stable operation in demanding environments.

VPH750-25/3P, AC750VSPD

VPH750-25/3P, AC750VSPD

The VPH750-25/3P, AC750V series SPD is designed for the critical role of primary surge protection in new energy plants, this product is a high-impedance Type 1 AC SPD. It is installed at the main AC distribution point (LPZ0/LPZ1 boundary) of wind or solar farms, where it intercepts and diverts the massive energy of direct lightning strikes, providing the foundational defense for the entire power generation and grid-connection system.

VPH385-30/4P, AC385V SPD

VPH385-30/4P, AC385V SPD

VPH385-30/4P, AC385V SPD is a high-capacity, low-voltage surge protective device (SPD) designed for Type 1 (Class B) installation at the main power inlet of low-voltage distribution systems, located at the boundary between LPZ0 and LPZ1 zones. It protects sensitive electrical equipment against damage from direct lightning strikes and induced transient overvoltages.

VPM385-80 3N+NPG, AC385V SPD

VPM385-80 3N+NPG, AC385V SPD

VPM385-80 3N+NPG, AC385V SPD belongs to the B-class three-phase AC power surge protector device, which is safe and reliable and has strong adaptability to the power grid. It can be widely used in various electrical occasions. It is used in the power distribution system from LPZ1 to LPZ2 zone to prevent the electrical equipment from being damaged by lightning strikes and transient overvoltage.

VPM220-10/T, AC385V SPD

VPM220-10/T, AC385V SPD

VPM220-10/T, AC385V SPD serves as a Category III transient overvoltage suppressor, designed for final-stage protection of single-phase 220-240V AC power supplies. Installed within the equipment being protected, it implements lightning protection from LPZ2 to LPZ3 zones according to the lightning protection zone concept. Providing both differential-mode and common-mode protection, it effectively safeguards LED lighting systems against damage caused by direct lightning strikes or induced transient overvoltages.

VP-24K4, AC32V SPD

VP-24K4, AC32V SPD

VP-24K4, AC32V SPD has two-wire signal surge protectors used in the LPZ0/1 and LPZ1/2 zones. Is mainly used to suppress surge overvoltage in a circuit, the signal from the interference of overvoltage, and avoid or reduce overvoltage of sensors, controllers and actuators.

VP-05K2, DC8V SPD

VP-05K2, DC8V SPD

VP-05K2, DC8V SPD adopts a multi-stage protection architecture. The front stage utilizes gas discharge tubes (GDTs) to withstand high lightning current impulses, while the rear stage employs low-capacitance TVS diodes for fast response speed. It provides protection for 1-pair and 2-pair lines, effectively safeguarding communication signal equipment from transient overvoltage interference and damage.

VPX05K05X-RJ45H48-8, DC8V SPD

VPX05K05X-RJ45H48-8, DC8V SPD

VPX05K05X-RJ45H48-8, DC8V SPD is a multi-port signal surge protective device engineered for high-density network protection with Power over Ethernet (PoE) support. It is specifically designed for installation at network switches, IP device endpoints, and communication cabinets in LPZ 2 to LPZ 3 zones (commonly referred to as Type 3 or Class D protection). It effectively safeguards sensitive network equipment such as IP cameras, wireless access points, and VoIP phones against damage from induced transient overvoltages on both data lines and PoE power lines.
