The CNC YC7-VA 2P V-A Protection Device is a smart relay that provides advanced protection and control for single-phase AC circuits. Designed for use in 40A and 63A systems, it monitors voltage and current in real-time and displays them on a digital interface.

It automatically disconnects the load when voltage exceeds or falls below user-defined thresholds and reconnects when conditions stabilize, following a programmable delay. This makes it ideal for preventing damage to sensitive electrical equipment due to voltage fluctuations or current overload.

The device uses microprocessor-based control with electromagnetic switching and supports a wide range of fault conditions. It’s suitable for residential, commercial, and industrial environments where system reliability is critical.

🛠 Installation & Operation:

1. Mount and secure the relay unit.

2. Connect wiring as per the schematic.

3. Set desired upper and lower voltage thresholds.

4. Configure delay time before reconnection.

5. Monitor voltage via the built-in digital display.
