63A Three-Phase Adjustable Voltage & Current Protector, Triple Digital Display Monitoring Relay with Phase Sequence & Unbalance Protection
Characteristics
This Three-Phase Adjustable Protector is a sophisticated power quality guard that monitors all three lines (L1, L2, L3) simultaneously. It ensures the safety of 3-phase motors and industrial systems through high-precision digital sensing.
● Triple Line Monitoring: Three independent LED screens display real-time voltage and current for each phase, providing a complete view of power status;
● Comprehensive Phase Defense: Protects against Phase Loss (Phase Failure), Phase Sequence Errors, and Voltage Unbalance;
● Wide Operating Range: Compatible with rated supply voltage AC 230V (Phase-to-Neutral) and supports a wide working range of AC 80V-300V;
● Programmable Thresholds: Includes adjustable settings for Voltage Unbalance Value (20-100V) and Action Delays to filter out temporary grid noise;
● Programmable Thresholds: Includes adjustable settings for Voltage Unbalance Value (20-100V) and Action Delays to filter out temporary grid noise;
● Color: Black;

Product Advantages
Motor Protection Specialist
Prevents motor burnout caused by phase sequence errors or unbalanced voltage, essential for expensive 3-phase machinery.
High Precision & Efficiency
Features RMS measurement with less than or equal to 2% accuracy and an asymmetric delay of 10s for stable performance.
Space-Saving DIN Rail Design
At only 65.31mm wide, this compact unit replaces multiple traditional meters and protection relays on the DIN rail.
Smart Auto-Recovery
Automatically restores power once the fault (like phase unbalance) is resolved and the recovery delay timer expires.
Application Scenario
- 3-Phase Motor Control
- HVAC & Industrial Chillers
- Elevators & Lifts
- Manufacturing Plants
FAQ
1
What happens if the phase sequence is wrong during installation?
The device will detect the Phase Sequence Error, the display will show "L1-L3-L2", and the protector will immediately disconnect the output to prevent motor damage.
2
Can I adjust the voltage unbalance threshold?
Yes. You can set the Voltage Unbalance Value (P8) from 20V to 100V and the corresponding recovery value (P9) to suit your specific equipment needs.
3
Does it monitor both voltage and current?
Yes, the triple display allows you to monitor the real-time Voltage and Current across the three phases simultaneously.
4
How do I know if an overcurrent fault has occurred?
The device features a Continuous Overcurrent Fault Indication and will disconnect the load while displaying the fault status on the screen.
5
Is it difficult to install?
Not at all. It features a standard 35mm DIN rail mounting and a clear wiring diagram (IN at top, OUT at bottom) for fast integration into any control panel.
