Self-Resetting Over/under Voltage Protector Jggq-63

I. Introduction

  The JGGQ-63 self-recovery over-voltage and under-Voltage Protector adopts a control circuit built around a high-speed, low-power microprocessor as its core and a magnetic latching relay as the main circuit, with a modular standard design. When the power supply line experiences overvoltage or undervoltage, the protector can quickly and safely cut off the circuit under sustained high-voltage impact, preventing abnormal voltage from being delivered to terminal electrical appliances and causing accidents. When the voltage returns to the normal value, the protector will automatically reconnect the circuit within the specified time, ensuring that terminal electrical appliances operate normally without supervision.

II. Features and Operating Environment

   1. When overvoltage or undervoltage occurs on a single-phase line, the line is disconnected. After the single-phase line voltage returns to normal, the line is automatically reset and reconnected after a delay, with no manual operation required.

2. When transient or temporary overvoltage occurs in the line, the protector will not maloperate.

3. When the line voltage becomes unstable due to faults such as loose contacts, or when power is suddenly cut off and then restored, the protector will not connect the line.

4. When the line fault voltage reaches its maximum, the protector itself will not be damaged.

5. Withstand impulse voltage: 4kV (complies with the safety standards for Class III appliances).

6. Ambient temperature: -25℃~40℃, relative humidity: 10%~90%, altitude not exceeding: 2,500 meters. The installation site shall be equipped with rainproof facilities.
