FAQ

Q: Is the Power Distribution Box supplied pre-wired and tested?

A: Yes. The units are factory assembled, labeled, and undergo electrical inspection processes including insulation resistance and continuity testing before shipment.

Q: Can the Power Distribution Box be used for motor loads?

A: Yes. Configurations with MCCBs and optional thermal overload relays or contactors can be provided for motor-related applications according to project requirements.

Q: Can international breaker brands be installed?

A: Yes. ABB, Schneider, Siemens, or Eaton breakers can be installed according to customer requirements. The final configuration and pricing depend on the selected components.

Q: What is the difference between IP54 and IP65 protection?

A: IP54 is commonly used for indoor industrial environments where protection against dust and water splashes is required. IP65 provides higher protection against dust and water jets and is suitable for outdoor or washdown environments.

Q: Can the Power Distribution Box be customized according to electrical drawings?

A: Yes. The engineering team can review electrical schematics, component specifications, and BOM information to support product configuration and quotation according to project requirements.
