In order to save costs, some high pressure electricity cabinet manufacturers often choose low-priced quality parts, which is very unfavorable for the later use of Assembly of Distribution cabinet. Below, I will introduce some knowledge about the selection of main components for Energy storage distribution cabinet, hoping to be helpful to everyone.

The user shall indicate the model, specifications, and brand of the main components such as the frame, circuit breaker, and transformer used when placing an order. Among them, from the perspective of their structure and functional use, circuit breakers are universal (also known as frame type, referred to as ACB in the world) and plastic shell type (MCCB is an international term, MCB (small)). According to the different protected objects, they can be divided into four categories:

1. Distribution protection type. Protect power sources and wires (wires, cables) and equipment;

2. Motor protection type. Special motors are not frequently started, and their operation is interrupted, as well as their protection against overload, short circuit, and undervoltage;

3. Protection in family or similar household settings. Protect lighting circuits, household appliances, etc;

4. Residual current (leakage) protection type. Used to protect people from the danger of electric shock and prevent electrical fires. Of course, in the process of technical disclosure, it is sometimes necessary to accept reasonable suggestions from manufacturers to avoid selecting technical indicators that far exceed the required distribution load, resulting in unnecessary investment, material waste, and increased maintenance costs.
