Air circuit breaker manual or automatic？

Air circuit breaker is a more complex switch, this switch function is particularly many, and manual, electric or automatic is relative to the function, that is to say, some functions are electric, some functions are manual, to Delixi Electric CDW3-1600 for example (Delixi Electric model circuit breaker using Schneider platform, From the design, process, parts quality and other links are introduced Schneider technology), the product has the following electric (automatic) functions:

1, electric operation pre-energy storage: when the electric operation is connected to the required power supply, electric operation can automatically give the frame circuit breaker mechanism for pre-energy storage, after the energy storage is finished, the circuit breaker has the energy required for closing;

2. Undervoltage trip: the undervoltage trip is connected to the main loop. When the voltage of the main loop is lower than a certain value, the undervoltage trip cannot be pulled, and the circuit breaker will automatically undervoltage trip.

3. Overload trip: the transformer collects the current parameters of the main loop and feeds the data to the controller, and the controller judges the current. When the current exceeds the set value, the controller sends a signal to the actuator, and the actuator performs switching operation.

In terms of simple frame circuit breaker, the switching function is manual, break-brake function if you want to in line under normal working conditions (not under voltage, overload trip) break-brake operations, also need manual operation, but the frame breaker general default assembling shunt closed electromagnet, can implement remote electric magnet by closing shunt close break-brake operations, if you need to automatic control, It is necessary to realize the automatic switching function by setting the switching conditions on the host computer of the circuit breaker.
