The CNC YC6VAs-3 63A Three Phase Voltage & Current Protector is a high-performance protection device engineered for modern electrical systems requiring stability, safety, and precision. Designed specifically for three-phase AC networks, this device continuously monitors voltage and current levels across all phases and instantly disconnects the load when abnormal conditions occur.
This protector supports adjustable over-voltage, under-voltage, and overcurrent settings, allowing users to customize protection thresholds based on system requirements. It features a digital display for real-time monitoring of voltage and current, enabling better control and system diagnostics.
With a rated current of 63A and wide operating voltage range (up to 400V AC for three-phase systems), it is suitable for industrial machinery, solar systems, generators, elevators, and commercial distribution panels.
The device also includes adjustable delay settings (trip delay and restart delay), ensuring safe reconnection and preventing frequent switching during unstable conditions. Its microprocessor-based design ensures accurate measurement and reliable protection, while the DIN rail mounting makes installation simple and efficient.
In addition to voltage protection, it also detects phase failure, phase imbalance, and incorrect phase sequence—critical for protecting motors and sensitive equipment. This makes it an essential component for maintaining electrical system reliability and preventing costly damage.
