Application & integration

Equipment assembly

Coordinate the switching or protective device with the panel drawing and load schedule.

Maintenance procurement

Use the full nameplate code and installed accessory list to make a precise replacement enquiry.

Manufacturer documents

Use the document for the complete order reference and delivered revision. Manufacturer links open the original source.

Prepare your enquiry

  1. Full order code and any existing nameplate or circuit schedule.
  2. Circuit voltage, load current, utilisation category and prospective fault level.
  3. Coil supply or trip characteristic; poles, auxiliary contacts and accessories.
  4. Coordination with upstream/downstream devices, installation outline and quantity.

A nameplate photograph or equipment list is enough to start. Mingkong provides component sourcing on enquiry; the offered brand, complete code, documentation and delivery terms are confirmed in the quotation.
