The terminal box provides a secure, insulated housing for electrical connections between the stator windings and external power cables. It protects these connections from environmental factors, mechanical damage, and electrical hazards, ensuring safe and reliable operation.
Common materials include thermoset plastics (e.g., phenolic resin), die-cast aluminum (e.g., AlSi12), and stainless steel. The choice depends on factors such as corrosion resistance, mechanical strength, and thermal requirements.
Typical IP ratings range from IP54 to IP68, indicating protection against dust and water ingress. Impact resistance ratings range from IK08 to IK10, indicating protection against mechanical impacts. Specific ratings depend on the application environment.
Selection involves considering rated voltage, rated current, conductor cross-section, cable entry size and number, terminal type, operating temperature, and environmental conditions. Always verify model-specific values with the legal manufacturer or supplier.
