1、 Scope of application
CYGQ45 self resetting overvoltage and undervoltage delay protectorAlso known asFully automatic reset overvoltage and undervoltage protectorSuitable for users or loads with single-phase AC voltage of 220V, frequency of 50Hz, and rated working current of 60A and below. As a protection for single-phase electrical equipment against overvoltage and undervoltage caused by neutral line faults. Mainly used for the protection of residential sub box incoming lines or distribution lines that require protection of single-phase electrical equipment.
The fully automatic reset overvoltage and undervoltage protector produced by our company controls the current, which is quite convenient for installation in the distribution box. The control circuit board is assembled with imported components, and the product is produced according to modular standards, with excellent performance and reliability. Can work normally under abnormal voltage conditions. When the mains voltage exceeds the set overvoltage action voltage value of the protector or is lower than the undervoltage action voltage value of the protector, the protector can quickly and reliably cut off the circuit to achieve electrical safety protection. When the mains voltage returns to normal, the protector can automatically delay the power connection and restore power supply, and all functions are automatically implemented without the need for personnel operation. The LED on the panel can indicate the working condition of the protector. The green light of the indicator light indicates the working power supply. When the red light of the indicator light is not on, the power supply is normal. When the red light is on, the protection function is activated to cut off the power supply.
The self resetting overvoltage protector has a compact structure, beautiful appearance, and is compatible with DZ47 (C45) guide rails for installation.

2、 Design principle of self resetting overvoltage and undervoltage delay protector
Fully automatic reset overvoltage and undervoltage protectorThe control circuit adopts a high-speed micro low power processor as the core, magnetic holding relay as the main circuit, and modular standard design. When overvoltage or undervoltage occurs in the power supply line, the protector can quickly and safely cut off the circuit under continuous high voltage impact, avoiding the occurrence of accidents caused by abnormal voltage entering the terminal electrical appliances. When the voltage returns to normal, the protector will automatically connect the circuit within the specified time, ensuring that the terminal electrical appliances operate normally without human supervision.
3、 Product characteristics of self resetting overvoltage and undervoltage delay protector
When a single-phase line experiences overvoltage, the line is cut off, and the single-phase line voltage returns to normal after a delay. The line is automatically reset and connected without manual operation.
When there is a transient or transient overvoltage in the circuit, the protector will not malfunction.
When the voltage of the circuit is unstable due to faults such as loose contacts, or when there is a sudden power outage and then a sudden power outage, the protector will not connect to the circuit.
When the line fault voltage is at its highest, the protector itself will not be damaged.
The protector exhibits inverse time limit action characteristics, with an action time of ≤ 1s.
Voltage protection range: 0-450V below 40A, 50/60A: 0-600V.
◆ Withstand impulse voltage: 4kV (in accordance with the safety standards of Class III electrical appliances).
The protector has a dual color LED to indicate the working status, with green indicating normal voltage; Red - indication of overvoltage or undervoltage or delay.
◆ Modular design of appearance, rail mounted installation.
◆ Wiring capability: Insulated wires of 25 square millimeters or less
