Frequent Asked Questions

  • What is the difference between Fixed Type and Draw-out Type ACBs?

    The Fixed Type is permanently mounted and is the most economic choice. The Draw-out Type consists of a main body and a drawer base. The main body can be "drawn out" for inspection or maintenance without disconnecting the main busbars, which is critical for systems requiring high reliability and safety.

  • What communication protocols do your Intelligent Controllers support?

    Sincede ACBs support standard Modbus-RTU protocol via RS485 interface. This allows seamless integration with BMS (Building Management Systems) or industrial SCADA systems for real-time monitoring of voltage, current, and fault history.

  • Do you offer OEM/ODM services for distributors?

    Yes, we have extensive experience working with global distributors. We can provide OEM services including custom logo printing, customized packing, and specific software settings for the controller to meet your local market regulations.

  • What is the warranty period for Sincede ACBs?

    We provide a standard 3-year warranty from the date of shipment. We are confident in our quality control. If any functional failure occurs due to manufacturing defects during this period, we will provide free spare parts or a complete replacement unit immediately.

  • How do you pack ACBs for export shipment?

    ACBs are heavy precision equipment. To ensure zero damage during sea or air freight, each unit is packed in a reinforced plywood case with high-density foam cushioning. This packaging is moisture-proof and shock-resistant, fully compliant with international export standards.

  • I am not sure which series fits my project. Can you help?

    Absolutely. You can send us your technical requirements (Amperage, Breaking Capacity, etc.). Our technical engineers will analyze your project and recommend the most cost-effective solution within 24 hours.
