Dual Power Automatic Transfer Switch Red Handle 125A Changeover Switch for Industry 400V More

The dual-power automatic transfer switch is composed of a two-unit miniature circuit breaker and accessories (auxiliary contacts, alarm contacts), mechanical interlocking transmission, controller and other components.The 63A specification is composed of miniature circuit breakers, which are especially suitable for lighting and small motor control equipment.
The switch is small in size, simple in structure, easy to operate, and has a long service life. The transfer switch is driven by a single motor, which is stable, no noise, and low impact.
It has mechanical interlocking and electrical interlocking functions, can be switched according to reliability, can be powered manually or automatically, and the rated current of universal and backup circuit breakers can be different.
A.T.S is equipped with user terminal blocks, which can reflect the status of the circuit breaker (open or closed); there are various instructions on the ats panel
Exquisite craftsmanship, isolation and anti-interference, stable performance, safe to use, widely used in homes, shopping malls, factories, laboratories, farms and other occasions

Working principle：
The power supply signal of this series of dual-power controllers and drive mechanisms depends on the A-phase and N-line of the input port of the ordinary switch or the standby switch.In the automatic state of the dual-channel power supply, when the common switching voltage of the incoming A and N channels is normal (ac190~240v), regardless of the common power supply B.C and backup switch A.b.Whether the c and N voltages are normal or not, the common switches will be closed first.At the same time, the power indicator light and the public shutdown indicator light are on.When the input common switch A phase and line N have no voltage, and the input standby switch A phase and line N voltage are normal, regardless of whether the normal switch B and the standby switch C voltage are normal, the dual-channel power supply is transferred to the standby.The power indicator light and the standby shutdown indicator light are on.Manual function, regardless of whether the ordinary power supply and the backup power supply have voltage, manual operation can be used.When operating manually, the manual-automatic button should be placed in the manual operation position.The push handle rotates clockwise to the terminal, the backup power supply is turned on R, and the common power supply is turned on N.When the push handle rotates counterclockwise to the terminal, the backup power supply air switch R is closed, and the common power supply air switch N is turned on
