  • Scope of Application

    TX45GQ-63 Voltage Protector is also known as automatic reset over voltage protection device and under voltage protection device. Applicable to he current or load for single-phase AC voltage 220V, frequency 50Hz, rated current 60A and below. As the single-phase line under-overvoltage caused by the neutral line fault to protect single-phase power equipment, it is mainly used for protecting residential household into the line or power distribution line of single-phase power equipment.
    TX45GQ-63 Voltage Protector (over voltage protection device and under voltage protection device) is 36mm wide, very convenient to be installed in the distribution box, the control circuit board select imported components, products with modular standard product, excellent performance and reliability. It can work in abnormal voltage conditions. When the utility voltage exceeds the overvoltage operation voltage value set for the over voltage protection device less than the undervoltage action voltage value of the under voltage protection device, the over voltage protection device and under voltage protection device can cut off the circuit quickly and reliably in order to keep the protection safe. When the mains voltage back to normal, the over voltage protection device and under voltage protection device can automatically delay the power on, restore power supply, all functions can be implemented automatically without manual operation. Light-emitting diodes on the panel can indicate working conditions of the protection. Indicator green light indicates working power, when the red light is off, it supply the normal power, when the red light is on, the protection function starts to cut off power supply.
    over voltage protection device and under voltage protection device have compact structure and beautiful appearance, can be installed with DZ47 (C45) rail.

    Model and Meaning

    Design Principles

    Automatic reset over voltage protection device and under voltage protection device uses high-speed micro-low-power processor as the core, magnetic latching relay as the main circuit, modular design of the standard, when the power circuit is in overvoltage or undervoltage, the protector can quickly and safely cut off the circuit quickly and safely under continuous high-voltage shock to avoid abnormal voltage into the terminal caused by electrical accidents, when the voltage returned to normal, the protector will automatically turn on the circuit within the specified time to ensure that the terminal is in normal operation in unattended conditions.

    Product Feature

    ◆ When single-phase line is in undervoltage, under voltage protection device will cut off line, after single-phase line voltage returned to normal by the delay, it wil reset to connected to the line without manual operation.
    ◆ When circuit is in transient or transient over-voltage, the over voltage protection device does not produce malfunction.
    ◆ When circuit is not real as the contact voltage instability, such as failure, or sudden power failure and a sudden call, the protector is not connected to the line.
    ◆ When circuit fault voltage is highest, the protector itself will not be damaged.
    ◆ Protector has inverse time action characteristics, action time ≤ 1s.
    ◆ voltage protection range: 40A below: 0 ~ 450V, 50 / 60A: 0 ~ 600V.
    ◆ Withstand impulse voltage: 4kV (in line with the safety standards Ⅲ class electrical appliances).
    ◆ Protection device has two-color light-emitting diodes indicating the working state, green - normal voltage indication; red - over-undervoltage or delay indication.
    ◆ Installation: 35mm rail installation, the appearance of modular design.
    ◆ Wiring capacity: 1P + N: 25mm ² and below insulated wire, 3P + N: 35mm ² and below the following insulated wire
    ◆ Standard: "Civil Building Design Code" JGJ-242 2011
    ◆ Ambient temperature: -5℃~40℃;
    ◆ Elevation: not more than 2000m;
    ◆ Humidity: the maximum temperature is 40℃ in the installation site , the relative humidity is not more than 50%, at lower temperatures, it can allow a higher relative humidity, such as 20 ℃ up to 90%. Special measures shall be taken for the condensation that is occasionally produced due to temperature changes.

    Direct control of the wiring: the electrical controlled is a single-phase power supply, its power consumption does not exceed the rated capacity of the controller, it can be controlled directiy, the wiring method as shown below.

    Outline and installation dimensions(mm)

    Instructions

    1, Correct wiring according to input (IN) and output (OUT) marked on the product (load power should be less than the rated power of the product).
    2, Two-color LED's state of lower wiring pattern on the self-duplex over-undervoltage delay protection's panel: After the product connects to the power, the red light is on, OUT does not output power, after delay protection 1min ~ 2min the green is on, OUT output power normally.
    3, Two-color LED's state of upper wiring pattern on the self-duplex over-undervoltage delay protection's panel: After the product connects to the power, ther red light is on, OUT does not output power, after delay protection 1min ~ 2min, the output indicate green light on, OUT output power normally.
    4, When the over-voltage or under voltage, the product into the protection state, the red light, automatically cut off the load power; When the voltage returns to normal, the delay 1min ~ 2min, green light is on, the product automatically connects to the load power supply and returns to normal output state.

    Announcements

    1, When product input end connects to the power supply for the first time, it need to delay 1min ~ 2min to supply power to the load .
    2, Wiring: N means the zero line, L means the line of fire, do not take the wrong.
    3, After the product connects to power, do not touch the live parts to avoid electric shock.
    4, In order to prevent contact heating under strong current, you must tighten the wiring terminal screws, otherwise, the contact will be heated to damage the product or cause other accidents because of too large contact resistance.

    Installation method

    Note: The main circuit power must be disconnected before installation or removal
