WGFK(G)-250V-60A Three-Phase Intelligent Hybrid Switching Device
The WGFK(G)-250V-60A is an intelligent three-phase hybrid switching device optimized for low-voltage reactive power compensation applications. Combining thyristor-based zero-voltage switching with magnetic latching contactor technology, it provides precise, reliable control of capacitor banks while eliminating harmful switching transients. Designed for 250V AC systems, it delivers enhanced performance and longevity for power factor correction in light industrial and commercial settings.
Core features
• Adaptive Hybrid Operation: Thyristors enable zero-voltage turn-on to eliminate capacitor inrush currents, while a low-loss contactor maintains steady-state connection.
• Intelligent System Protection: Integrated over-temperature, phase-loss, and current imbalance detection with automatic safety response and fault logging.
• Low Operational Overhead: Minimal holding power requirement (< 2.5W per phase) reduces panel heat generation and operating costs.
• Extended Service Life: Solid-state switching action prevents contact arcing and mechanical wear, offering 300,000+ operational cycles.
• Streamlined Integration: Compact DIN-rail mountable design with universal control voltage compatibility (DC 12V/24V or AC 220V).
