TBBQ12 Series

Medium-voltage Automatic Transfer Switch
TBBQ12 series medium voltage automatic transfer switch is TYT's medium-voltage automatic transfer switch with leading technology, rated voltage 12kV, rated current covering 630~2000A, breaking current up to 31.5kA, with TBBQ12 component type and KYN28-12-Q12 assembled type, with optional pull-out bypass function, etc., which is widely used in key industries such as data communication, energy industry, medical and high-rise buildings to ensure reliable and stable operation of medium-voltage power.

Product Features

Dual Interlocks for Safe and Reliable


● Internal mechanical hard interlock transmission, preventing simultaneous closing of the main and backup power supply by misoperation
● Auxiliary switch and permanent magnet mechanism control loop with electrical interlocking and dual safety to ensure reliable


Fast Conversion, and Continuous Assurance


● Permanent magnet drive mechanism, with conversion time less than 200ms and high continuity of power supply
● Short-time power-on action, with no need to wait for energy storage, greatly improving service life


Mechanical Closing, and Emergency Switching


● Manual in-place conversion of external linkage for emergency standby control and service operation
● To meet the safety specifications of the grid company in situ reversal, regardless of faults in secondary lines, internal capacitance, etc.
