signal lightning arrester

LS-W2L Series Ultra-Thin 2-Wire Control Signal Lightning Arrester (Line-Line Mode) is designed for communication equipment such as dedicated communication lines, telemetry signals, measurement and control signals, PLC analog control systems, and 4-20mA current loops. Suitable for installation in LPZ 2-3 and subsequent lightning protection zones, it provides line-line mode fine protection for two signal lines.Featuring an ultra-thin design (7mm thickness), the product saves

Description This system is designed for monitoring and intelligent management of surge protectors, including recorded lightning strike counts, strike duration, remote signaling data, status of pre-breakers, and operational status of lightning arresters.Features • Display lightning arrester discharge count and status of two switch signals online • Microprocessing and digital storage ensure accurate data recording, interference-free operation, and data retention during power

Product Features● One channel NTC acquisition port: measure the surface temperature of SPD, with ultra/low temperature alarm function, threshold can be set, and independent alarm indicator can record 30 times (register reading) of alarm times and the date and time of alarm occurrence.● One lightning surge collection port: monitoring line surge current, triggering threshold of 500A, T1/T2/T3 compatible. The surge count is displayed locally for 0-9999 times, and the register

3+NPE topology surge arrester built for three-phase five-wire TN-S and TT power systems, with separated phase-earth and neutral-earth discharge paths to avoid unbalanced neutral current issues seen on standard 4P SPDs. Classified as combined T2+T3 fine protection for LPZ1-LPZ2 terminal panels, carrying 20kA nominal and 40kA max surge capacity to withstand repeated lightning impulses. Vibration-proof pluggable modules fit continuously vibrating production cabinets, front

Product Description 4-pole Type 2 SPD fits three-phase power distribution systems in commercial buildings, mounted on floor secondary panels within LPZ0B-LPZ1 zones to shield lighting, air conditioning, CCTV and office electronics from induced lightning surges and grid voltage fluctuations. Multiple Uc ratings (275/320/385/440Vac) match global commercial mains standards. Pluggable modules simplify property maintenance replacement, V0 flame retardant housing mitigates cabinet

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

Product Description Conventional SPDs without remote contacts rely entirely on manual inspection; degraded failed modules operate undetected and leave downstream equipment unprotected. This 4-pole surge protection device integrates NC/NO switching remote contacts to send automatic switch alarm signals to automation monitoring platforms upon SPD failure, paired with front visual status window for on-site check, delivering dual local & remote monitoring. With 40kA surge

Product Description Type 2 surge protective device exclusively designed for 440Vac high-voltage three-phase distribution systems, installed in heavy-duty industrial control cabinets and large commercial secondary panels within LPZ0B-LPZ1 zones. It diverts lightning and grid switching surges with voltage protection level ≤ 2.0kV to safeguard large inverters and power control cabinets. 4-pole full L1/L2/L3/N-E circuit protection with 40kA maximum discharge capacity handles
