surge protection devices spds

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 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

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 Features Single-port full-mode surge protection: Safeguards all line paths (L-N, L-E, N-E) against transient overvoltages. Ultra-compact & tool-free installation: Miniature dimensions (42mm30mm23mm) enable quick parallel mounting at equipment front ends. IP67 environmental protection: Dust-tight and waterproof enclosure ensures stable performance in harsh outdoor conditions. LPZ 2-3 zone compatibility: Designed for installation in LPZ 2-3 and subsequent

Product features Full mode protection No leakage current, no afterflow Large flow capacity and super low residual pressure Suitable for installation in LPZ 1-2 and subsequent lightning protection zones, suitable for fine lightning protection devices in three-phase power supply systems. Product Specification Standards IEC 61643.11 SPD type T2,T3 Models SLV-40T SLV-80T Nominal operating voltage Un 220Vac(50Hz) Maximum continuous operating voltage Uc 320Vac(50Hz) Nominal

Product Description Overseas industrial and commercial distribution projects enforce strict electrical compliance rules; units without TUV & CE certification fail local engineering acceptance inspections. This 4-pole Type 2 SPD fully passes TUV safety testing and CE EU EMC certification, manufactured strictly to IEC 61643-11 international low-voltage surge standard with third-party laboratory validation on 8/20 s surge current, residual voltage and discharge capacity. V0

Product description Designed for installation in LPZ 2-3 and subsequent lightning protection zones, this fine-wire lightning arrester delivers dedicated lightning protection for end-level equipment in both AC and DC power systems. It is typically installed in series at the front of the protected equipment to clamp transient overvoltages effectively. Product features Full-Mode Surge Protection: Dual-port design provides comprehensive protection against all surge modes,
