INTELLIGENT SURGE PROTECTIVE DEVICE

New Products / New Technology

GP-iSFB Intelligent Surge Protective Device (SPD) features a modular all-in-one design that integrates intelligent monitoring, backup protection, and surge protection functions. Utilizing patented ECD technology, it accurately distinguishes between lightning surge currents and power-frequency follow currents, effectively preventing SPD combustion accidents. The device continuously monitors real-time dataincluding voltage, temperature & humidity, leakage current, lightning strike parameters, and SPD full-lifecycle predictive assessmentand transmits all information to the "Intelligent Lightning Protection Monitoring Management System" platform. Key advantages include space-saving compact modular construction, low residual voltage, and clear local display, ensuring both safety and operational convenience.

SURGE PROTECTIVE DEVICE

GPU1-C Series Surge Protective Device is designed for environments with moderate lightning intensity. Using the 8/20μs waveform as the test benchmark, it provides reliable Class II surge protection. At its core, high-performance zinc oxide varistors deliver high surge current capacity and low residual voltage, effectively clamping overvoltages. To address component aging caused by repeated surges, the device incorporates intelligent thermal protection that continuously monitors the varistor status and achieves physical isolation upon degradation, complemented by an intuitive indicator window for easy maintenance. The product features high surge current capability and low residual voltage, supports multi-level combination configurations to suit various power supply systems, and offers complete thermal disconnection capability with patented thermal trip technology. Fault indication is standard, with optional remote signaling available.

SPECIFIC PROTECTIVE DEVICES FOR LOW-VOLTAGE SURGE PROTECTIVE DEVICES

GP-BP Series SPD Dedicated Protective Device (SSD) employs patented innovative technology. Connected in series with the SPD circuit, it accurately distinguishes between lightning currents and power-frequency follow currents: it remains non-tripping under lightning surge strikes while promptly tripping under low power-frequency currents, effectively preventing SPD combustion or explosion. The maximum breaking capacity reaches 100kA, with a power-frequency fault protection rating of 3A (Ii), fully compatible with T1, T2, and T3 class SPD applications. Each phase features independent tripping with remote signaling fault alarm capability, enabling remote monitoring and ensuring a safe and controllable system.
