Product Advantages
Highly Versatile Performance
Highly compatible with any standard enclosures, including MNS, GCK, GGD, and other configurations.
Comprehensive Protection Functions
Featuring multiple safety protection functions—including overvoltage, undervoltage, voltage loss, overcurrent, phase failure, short circuit, and harmonic protection—it effectively ensures the safe operation of compensation capacitors and other electrical equipment, significantly extending their service life.
Precise & Secure Control
Utilizing voltage zero-crossing triggering, it eliminates inrush current during switching-in, and achieves zero-crossing cut-off to prevent high-voltage spikes during disconnection.
Intelligent Control & Management
It supports automatic control and remote monitoring, with built-in functions for data acquisition, analysis, storage, and report generation. This allows users to easily monitor and manage the operational status of the power grid.
