Overview
The UEY1 series Automatic Reset Overvoltage Protectors features a high-speed, low-power microprocessor as its core control circuit, with a magnetic latching relay as the main circuit. It is designed with a modular standard approach.
When the power supply line experiences over-voltage or under-voltage, the protectors can quickly and safely cut off the circuit under continuous high-voltage impact, preventing abnormal voltage from being sent to the terminal electrical equipment, thus avoiding accidents.
When the voltage returns to normal, the reset overvoltage protectors will automatically reconnect the circuit within a specified time, ensuring the normal operation of the terminal electrical equipment under unattended conditions.
Product Description
Automatic Reset Overvoltage Protectors
Overvoltage Protectors features 1:
– The single-phase line is cut off when the over-voltage occurs. The single-phase line voltage returns to normal after a delay, the line is automatically reset and connected without manual operation
– When transient or transient overvoltage occurs in the line, the overvoltage protectors will not cause misoperation
Overvoltage Protectors features 2:
– When the overvoltage protectors are unstable due to the fault of the line such as false contact, or the sudden power failure and sudden call, the overvoltage protectors do not connect the line
– When the line fault voltage is the highest, the protector itself will not be damaged
Overvoltage Protectors features 3:
– The overvoltage protectors are segmented and inverse time limit, and the overvoltage and undervoltage operation time meets the standard JB/T 12762-2015
– The overvoltage protectors use leds to indicate the working status, green – power indicator, red – overvoltage indicator
Overvoltage Protectors features 4:
– Yellow – Undervoltage indicator, blinking red or yellow – Delay recovery on indicator
– Withstand impulse voltage: 4kV (in line with Class III electrical safety standards)
– Modular shape design, rail installation

Automatic Reset Overvoltage Protector Advantages
1. Compact and Durable Design: It features a compact design that is durable and can be easily installed in standard cabinet-style distribution cabinets.
2. High Current Interrupting Capacity: These protectors have a strong ability to interrupt high currents, with some models capable of handling up to 150kA.
3. Rich Maintenance Functions: The logic controller, acting as the brain of the protector, offers a variety of adjustable protection parameters, including over-load long-time delay, short-circuit short-time delay, short-circuit instantaneous, and ground fault protection.
4. Automatic Reset: After the voltage returns to normal, the protector can automatically reconnect the circuit without the need for manual operation, making it suitable for unattended environments.
5. Prevention of False Tripping: The design ensures that the protector does not falsely trip during transient or momentary over-voltages.
6. Safe Operation: It can quickly and safely disconnect the circuit under continuous high-voltage stress, preventing abnormal voltage from causing accidents in terminal electrical equipment.
7. High Surge Voltage Tolerance: The protector is capable of withstanding high surge voltages, complying with the safety standards for Class III electrical equipment.
8. Status Indication: It includes dual-color LED indicators to clearly show the working status, with green indicating normal voltage and red indicating over-voltage or under-voltage conditions or delays.
9. Modular Design: The protector has a modular design that facilitates rail mounting, enhancing installation efficiency and uniformity.
10. Wide Range of Applicability: It is suitable for a variety of voltage and frequency ranges, meeting the usage requirements of different regions and electrical equipment.
