Company News, News 2025-11-28
Reliable Protection for Every Power System
Three-Phase Over/Under Voltage Protector is designed to provide comprehensive safety for industrial and commercial electrical systems.
With intelligent monitoring, flame-retardant materials, and flexible customization options, it ensures stable operation and long-term reliability across every application.
1. Multi-Layer Protection: Voltage & Current Safety
The continuously monitors three-phase voltage and current to detect anomalies instantly and react in milliseconds.
Overvoltage Protection — Cuts off the circuit when voltage exceeds the preset limit, preventing equipment burnout.
Undervoltage Protection — Disconnects power supply when voltage drops too low, avoiding unstable operation.
Overcurrent Protection — Automatically isolates overloaded circuits to prevent overheating and insulation damage.
This smart protection system ensures that your equipment remains safe from the most common power-related faults.
2. Flame-Retardant & Durable Housing
Built from high-quality flame-retardant materials,The maintains safety even under extreme conditions.
Its enclosure resists heat, deformation, and electrical arcing — ensuring durability, stability, and long service life in industrial environments.
3. Customizable for Your Brand
Every detail of the Voltage Protector can be personalized to match your brand identity:
- Button color customization — Choose from multiple color options (blue, red, green, black, silver).
- Front-panel logo printing — Add your brand name or logo for OEM/ODM collaboration.
- Parameter presets — Configure voltage and current thresholds to meet local standards (220V/380V, 230V/400V, etc.).
This flexibility makes the ideal for distributors and manufacturers seeking OEM voltage protection solutions.
4. Intelligent Auto Reset Function
When voltage returns to normal levels after a fault, the automatically resets and restores power — no manual intervention required.
This ensures uninterrupted operation, reduces downtime, and enhances overall system efficiency.
