Function:
1. 2 Circuit Breakers The double circuit breaker consists of a miniature circuit breaker with two units and accessories (auxiliary contact, alarm contact). The rated current of general and standby circuit breakers may be different.
2. Manual or Automatic Control The power transmission switch has mechanical locking and electrical locking functions with high reliability and can be powered manually or automatically.
3. Single Motor Drive: The switch is driven by a single motor, which is stable, noiseless, low impact, compact, easy to set up and convenient to use.
4. Easy Observation The automatic dual power switch is equipped with user terminal blocks, which can reflect the circuit breaker status (on or off), and there are different indicators on the control panel.
5. Wide Purpose The switch adopts excellent technology, insulated anti-interference, high stability, widely used in families, shopping malls, factories, laboratories, farms and other occasions.
Specification:
Item type: dual power automatic transfer switch.
Material: PC.
Rated current: 63 A.
Rated voltage: 400 V AC.
Frequency: 50 Hz.
Number of poles: 4P.

Working principle:
The power supply signals of the dual power supply controller and drive mechanism depend on the A phase and the N conductor of the incoming port of the common switch or standby switch. If in the automatic state of the two-way power supply, the voltages of the common switch of the incoming phase A and N are normal (AC190-240V), the common switches are preferably closed, regardless of whether the voltages of the common power supply B C and the standby switch are a b c and N are normal.
