signal surge protective device

LS-CS5L Series 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 integrated module structure, the product supports 35mm DIN Rail

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

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

LS-10G/LS-10G/POE is a high-speed RJ45 network signal surge protector designed for 10G/10G BASE-T 802.3 computer network information systems, suitable for installation in LPZ 2-3 and subsequent lightning protection zones. It provides comprehensive protection against surges in network signal lines, ensuring stable data transmission even in harsh electromagnetic environments.Featuring a modular design with a metal casing, the product offers strong anti-interference ability,

Product Description Conventional surge protection devices require regular cabinet disassembly for internal inspection, raising labor costs and production downtime losses. This 4-pole SPD implements dual status monitoring: front green/red window enables instant on-site visual checks, while passive remote contacts transmit fault alerts to central control platforms without frequent cabinet opening. Pluggable modular design accelerates faulty unit replacement without full panel

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

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 This 4-pole Type 2 surge protection device is engineered for 320Vac three-phase distribution systems, mounted in LPZ0B-LPZ1 distribution cabinets. With 40kA maximum discharge capacity, it diverts heavy lightning surges and limits voltage protection level ≤ 1.5kV to prevent transient overvoltage damage on industrial controllers and building power meters. Anti-vibration modular structure fits constantly vibrating factory cabinets, with built-in thermal

LS-CHE Series 2-Wire Control Signal Lightning Arrester (Line-Ground 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-ground mode fine protection for two signal lines. Featuring a plug-in module design, the product allows for easy replacement
