Product Features Independent integrated module for each pole Built-in ultra-low temperature release mechanism Equipped with

LPM 40-385/4 Series is a T2 level power surge protector designed for three-phase power supply systems. It is specifically tailored for industrial and commercial power systems, providing reliable protection against transient overvoltages caused by lightning strikes and power grid fluctuations. Product features Independent integrated module for each pole Built-in ultra-low temperature release mechanism Equipped with indication windows and remote signaling contacts

LS-100M Series Rack-Mount Network Signal Surge Protectors are designed for 100 BASE-T 802.3 computer network systems, suitable for installation in LPZ 2-3 and subsequent lightning protection zones. They feature a standard 19 1U rack design, making them ideal for high-density low-speed network environments such as security monitoring rooms and small data centers. Integrated with multi-channel independent protection circuits, the products minimize mutual interference between

Product Description 4-pole Type 2 SPD engineered for three-phase industrial automation cabinets, installed in LPZ0B-LPZ1 secondary lightning zones to protect PLCs, inverters and servo systems from lightning surges and grid switching transient overvoltage. Full L1/L2/L3-N-E circuit diverts surge currents with 25ns fast response to clamp dangerous high voltage. Operating temperature range -40 to +70 fits cold workshops and hot equipment rooms, anti-vibration modular

Product Description Three-phase auxiliary distribution cabinets inside EV charging stations are vulnerable to lightning induced surges and grid switching impulses, which cause charger mainboard and metering module breakdowns and downtime. This 4-pole Type 2 SPD is mounted in LPZ0B-LPZ1 secondary panels within charging stations, diverting lightning transient currents with 40kA surge capacity and clamping residual voltage within safe limits via 25ns fast response to protect

Product Description Laboratory precision measuring instruments are highly sensitive to voltage fluctuations and lightning surges; transient high voltage causes sensor calibration drift and permanent circuit damage. This 4-pole Type 2 SPD is installed on lab three-phase incoming distribution panels. The low voltage variant delivers residual voltage as low as 1.25kV with 25ns nanosecond-level response to divert surge currents and contain impulse voltage within instrument

Product Description Induced lightning surges and grid switching transients often burn industrial mainboards, inverters and building low-voltage hardware. This 4-pole three-phase SPD acts as secondary protection in LPZ0B-LPZ1 cabinets, conducting and diverting surge currents within 25ns to clamp residual voltage to safe ranges and reduce overvoltage breakdown risks for downstream electronics. 40kA maximum discharge capacity withstands repeated heavy lightning impulses; anti

Dual-function combined SPD integrating Type 2 high-current diversion and Type 3 precise voltage clamping, installed at LPZ1-LPZ2 terminal zones and coordinated with front Type 1 arresters for staged surge suppression. 25ns nanosecond phase response instantly blocks grid switching voltage spikes, two Uc variants match regional impulse withstand requirements. Vibration-resistant modular build reduces loose contact risks on production lines, standardized 5Nm torque enables

Product Description Integrated non-detachable SPDs require full removal and complete rewiring upon failure, increasing maintenance time and loose wiring risks. This SPD adopts split base + independent pluggable module structure: when one module degrades, only the faulty unit needs extraction and replacement with all base, phase and PE wiring untouched to cut on-site wiring labor. Anti-loose locking buckles resist long-term cabinet vibration, while each single module
