tbbq2 series (cb)

dual-power transfer switch
tbbq2 series adopts the circuit breaker produced by tyt with more than 40 years of manufacturing experience as the actuator and is equipped with an integrated smart controller. when a fault such as undervoltage or shortage is detected, it can automatically switch to the backup power supply; it has short-circuit and overload protection functions, meeting the requirements of the electrical circuit for selective protection. its breaking capacity is much larger than that of the dual-power transfer switch composed of other components such as contactors, featuring high safety and reliability, and is suitable for use in lines with ac 50hz, rated voltage up to 400v and below, and rated current up to 630a and below.
