    Characteristics and functions

    TXQ5 Automatic Transfer Switch (hereinafter referred to as the auto transfer switch) is a new generation of CB-class products with advanced digital electronic control technology. The Automatic Transfer Switch has the characteristics of small volume, energy saving, easy installation and reliable interlock protection, functions are advanced and complete.

    5.1 Small volume

    Single motor drive structure, the use of positive and negative rotation of the motor to achieve the conversion function, while reducing the height of the product, reducing the installation space.

    5.2 energy saving

    The Transmission mechanism uses the motor drive mode, the power consumption is low and the noise is small.

    10W 7W 9W 20W

    5.4 Double interlock protection

    5.5 Isolation function

    Use double protection of mechanical interlock and electrical interlock, to prevent that two power supply are connected at the same time, thereinto, electric interlock uses the method of directly indicating circuit breaker contact position of the automatic switch, to achieve the true meaning of the electrical interlock 一 to avoid automatic conversion in the situations of contacts welding, circuit breaker handle damaged, circuit fault, circuit breakers tripping and others.

    5.5 Isolation function

    TXQ5 Automatic Transfer Switch (except TXQ5B-63) have isolation function.
