GLSV‑ZNH1‑12 Smart Phase-Controlled Circuit Breaker is a high-performance vacuum circuit breaker designed specifically for 12 kV nonlinear load applications, supporting precise phase-selection switching and non-full-phase operation. It effectively suppresses magnetizing inrush currents and switching overvoltages.
The breaker adopts a three-phase independent permanent-magnet operating mechanism, achieving action time dispersion within ±0.5 ms, ensuring excellent synchronism and operational stability.
It features intelligent functions such as event logging, operation waveform recording, and coil monitoring. With manual tripping capability, a built-in energy storage module, and low-power operation, it is ideally suited for the intelligent protection and control of key loads such as transformers, capacitor banks, and reactors.
