The present invention relates to a power distribution panel, especially a power distribution panel with selectable output voltage.

Power distribution panels are widely used in power distribution systems, and their main purpose is to distribute electrical energy from an input power source to loads through circuit breakers. A power distribution panel typically contains a plurality of circuit breakers, and a plurality of brackets for mounting the aforementioned circuit breakers. Each bracket is electrically connected to the input busbars, and the input busbars are electrically connected to the same input power source to provide a specific voltage to the circuit breaker associated with the bracket. Under normal circumstances, after the circuit breaker is turned on, the power it receives will be transmitted to the load. In the event of an overcurrent condition, the circuit breaker automatically opens to cut off the electrical connection path between the load and the incoming power source.

However, in the case where the above-mentioned input busbars are all connected to the same input power source, a plurality of loads can only receive the same voltage from the power distribution panel, that is, the corresponding voltage cannot be provided according to the actual demand of different loads. Elasticity is low.

Therefore, how to develop a power distribution panel that can improve the above-mentioned conventional technology is an urgent need at present.

The power distribution panel has a circuit breaker module, including a circuit breaker and an adapter. The circuit breaker is electrically connected to one of the input busbars through the adapter assembled with it; and when the circuit breaker is not assembled with the adapter When the adapter is removed from the circuit breaker, the circuit breaker is electrically connected to the other input busbar. Therefore, the circuit breaker can be selectively coupled to one of the two input bus bars through whether the adapter is assembled or not, and the power distribution panel can provide two different output voltages, which improves the flexibility of application.

To achieve the above object, the present invention provides a power distribution panel, which includes a first input busbar, a second input busbar, a plurality of brackets and a plurality of circuit breaker modules. The first input bus bar and the second input bus bar are respectively coupled to the first power source and the second power source. The plurality of brackets are electrically connected to the first input busbar or the second input busbar. The plurality of circuit breaker modules are respectively assembled with the plurality of brackets. Each circuit breaker module includes a circuit breaker and an adapter, and the adapter is detachably assembled with the circuit breaker. In any circuit breaker module and its corresponding assembled bracket, when the adapter is not assembled with the circuit breaker, the circuit breaker is electrically connected to the first input busbar, and when the adapter is assembled with the circuit breaker When the circuit breaker is electrically connected to the second input busbar.
