Introduce
Self resetting overvoltage and undervoltage protector is an intelligent electrical protection device widely used in single-phase and three-phase power supply systems. It can automatically monitor the voltage status of the power grid and provide reliable protection under abnormal conditions.
K52-2066 Overvoltage And Undervoltage Protector
The K52-2066 is a compact DIN-rail meter for accurate voltage and current monitoring. It features a clear LED display and is designed for reliable performance in various electrical measurement applications.
Key Features
- Overvoltage protection: When the voltage exceeds the set range (such as single-phase 230-300V, three-phase 390-500V), the circuit will be automatically cut off.The default overvoltage protection value is 280V (single-phase)/overvoltage protection action time is adjustable from 0.1-30s.
- Undervoltage protection: When the voltage is below the set threshold (such as single-phase 210-140V, three-phase 370-260V), the protection mechanism is activated, and the default undervoltage protection value is 160V (single-phase).
- Overcurrent protection: Supports adjustable protection values of 0.5-63A, with continuous overcurrent protection times set (1-20 times/OFF).
- Self recovery function: After the fault is eliminated, the power supply will be automatically restored with a delay time of 1-600S, which can be set.
- Multiple Display: Real time display of parameters such as voltage, current, and battery level, with some models supporting power factor measurement.
Applications
- Residential power distribution system protection
- Industrial equipment power protection
- Power monitoring in commercial premises
- Protection of important load equipment
This series of products adopts modular design, with fast response speed (protection action time as short as 0.1S), high measurement accuracy (voltage error ≤ 2%), flexible settings, etc., which can effectively prevent equipment damage caused by abnormal grid voltage and ensure electrical safety. All models have power-off memory function, and the set parameters can still be maintained after power-off.

FAQ
1. Is the K52-2066 suitable for single-phase or three-phase power systems?
The K52 series includes protection options for different power systems. Please provide your supply voltage and wiring configuration when inquiring, so we can confirm the correct K52-2066 configuration for your application.
2. Can the overvoltage and undervoltage protection thresholds be adjusted?
Yes. The protection thresholds can be set to suit the application. Please share your nominal supply voltage and the required trip values so we can confirm the available setting range for the K52-2066.
3. Does the K52-2066 provide overcurrent protection?
The product series includes adjustable overcurrent protection. To confirm the appropriate configuration, please provide the load’s rated current and, if applicable, its starting current.
4. Will the protector reconnect automatically after the voltage returns to normal?
Yes. The self-recovery function restores power after the fault clears, following a set delay. The product page lists an adjustable recovery delay of 1–600 seconds; please confirm the required setting for your project when ordering.
5. What information is needed to select the right K52-2066 for a distribution panel?
Please provide the supply voltage, single-phase or three-phase wiring, load current, required protection thresholds, and available DIN-rail space. A wiring diagram or panel layout will help us confirm the configuration and installation requirements.
