63A Three-Phase Automatic Protector with Smart Phase Switching
Protects three-phase equipment against voltage variations, with individual phase adjustment and automatic switching. Ideal for industrial, commercial, and residential installations where electrical stability is critical. Simple DIN rail mounting, quick configuration via buttons, and a clear digital display.
What you get with this product
- Continuous protection for expensive equipment — prevents damage to motors, pumps, and sensitive appliances caused by overvoltage or undervoltage
- Individual adjustment for each phase — set minimum and maximum thresholds exactly to your needs, between 160V and 280V per phase
- Real-time visualization — LED display shows voltage on all three phases simultaneously, instantly identifying network issues
- Smart automatic reconnection — after voltage normalizes, the system resumes power after your set interval (5-630 seconds)
- Quick installation without modifications — mounts directly onto a standard DIN rail in the electrical panel, with clear marked connections N, L1, L2, L3
- Savings through prevention — avoid repair or replacement costs for equipment damaged by electrical fluctuations
How it works and how to install it
The device continuously monitors the voltage on each of the three phases. When the voltage goes outside your set range, the integrated relay automatically cuts off the power. After the voltage returns to normal and the set delay time expires, it automatically reconnects the circuit. Installation is done by mounting it on a 35mm DIN rail in the electrical panel, connecting the N, L1, L2, L3 wires according to the diagram on the housing. Thresholds and delay times are configured via the side buttons, with values instantly visible on the LED screen. No special tools or advanced electrical knowledge are required.
Frequently Asked Questions
Can I use the protector if I only have two active phases in the installation?
Yes, the device also works with two active phases. It monitors each connected phase independently and provides protection even in two-phase configurations.
How quickly does it react to an overvoltage?
The protector detects and cuts off power within a maximum of 0.1 seconds from an out-of-threshold voltage occurrence, preventing equipment damage.
Does it reset automatically or do I need to intervene manually after an interruption?
Reconnection is automatic after the voltage normalizes and the set delay time expires. It does not require manual reset, ideal for unattended locations.
