How to choose the suitable medium voltage circuit breakers?

1. Requirement Analysis: Determine the system voltage, short-circuit current, load list, and environmental conditions.

2. Scheme Design: Draw a single-line diagram, determine the main wiring scheme, cabinet type (input, output, interconnection, etc.).

3. Specification Compilation: List in detail the technical parameters, standards, and brand requirements for each circuit and each component.

4. Component Selection:

· Circuit Breaker: Verify the breaking capacity, rated current, and trip curve.

· Transformer: Determine the transformation ratio, accuracy class, and capacity.

· Busbar: Calculate the current carrying capacity, determine the material and insulation.

· Protective Device: Match the protected object and select the communication protocol.

· Cabinet Structure: Determine the protection level, internal arc level, and size.

5. Integration Verification: Ensure that all components are compatible in physical installation, electrical interfaces, and control logic.
