ParameterReference data
IEC family current range16–1600 A across separate frames
Frame selectionXT1 through XT7
Trip technologiesThermal-magnetic or electronic, depending on frame and version
Installation optionsFixed, plug-in or withdrawable; availability depends on frame
Regional versionsIEC and UL/CSA versions require separate order-code checks

The family current range is not one breaker rating. Specify rated voltage, poles, Icu/Ics at that voltage, trip settings, coordination and installation version. An IEC selection does not establish UL/CSA suitability.

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.
