Where Components Fit Inside the Cabinet
Use the cabinet position first, then choose the matching product group. This map is for component group selection, not for electrical circuit design.
Application Fit by Cabinet Position
Confirm the cabinet zone before comparing model data. This keeps similar-looking components from being matched to the wrong bay or interface.
For breaker contact interfaces, busbar wall passages, phase barriers and insulated mechanism links inside MV bays.
For drawout truck contacts, fixed connection points, tulip contacts and busbar support hardware in the main circuit.
For grounding knives, linkage parts and interlock mechanisms tied to safe earthing operation.
For secondary plug interfaces, electromagnetic locks and door hardware on control and interlock circuits.
For anti-condensation heating, cable exits, termination support and protection around cabinet service compartments.
For embedded poles in the breaker compartment, contactor positions and protection fuse holders that must match the cabinet layout.
Selection Matrix for Replacement and RFQ
Use this matrix to choose the first product group before sending drawings, photos and rating information.
| Need or cabinet position | Start with product group | Confirm before RFQ | Drawing need |
|---|---|---|---|
| Breaker contact insulation or spout | Voltage class, current rating, cabinet type and outline size | Product photo plus mounting drawing | |
| Wall-through insulation or busbar passage | Voltage class, hole pattern and conductor interface | Drawing strongly preferred | |
| Drawout current path or contact replacement | Breaker model, rated current, contact style and installation position | Product photo plus dimensions | |
| Auxiliary control or interlock part | Plug pins, lock voltage, panel cutout and installation side | Photo plus measured dimensions | |
| Cabinet service fitting | Cabinet position, clamp size, cable exit size and quantity | Dimensions when fixed mounting matters | |
| VCB service or MV protection part | Breaker or contactor model, voltage, current or fuse rating | Model drawing or label photo |
Drawing and Data Review
Component matching should not rely on appearance alone. Photos, drawings, labels and measured dimensions work together; teams can also download switchgear component catalog PDFs before matching drawings and labels.
Use product photos for shape
Photos help identify the replacement family, visible interface and cabinet position.
Use drawings for fit
Drawings confirm outline size, hole positions, terminals, mounting direction and fixed dimensions.
Do not infer rating from appearance
Voltage class, current rating and compatibility must be checked against labels, drawings or technical data.
Send measured data when drawings are missing
If a drawing is not available, include measured dimensions, cabinet photos and the required outline drawing request.
RFQ Checklist for Engineers and Procurement
Send the part evidence first. XIYA POWER can then check the component group, drawings and missing data before price discussion, or check certificates, test reports and RFQ forms when project files need review.
- Product group or old part name
- Clear product photo and cabinet photo
- Cabinet model or breaker model
- Rated voltage, current and duty if known
- Mounting dimensions or drawing
- Quantity and destination standard
- Match product group and cabinet position
- Check drawing need and missing dimensions
- Confirm rating data before price discussion
- Matching product group
- Available model photos or drawing previews
- Required missing data before final quote
- Quotation scope based on confirmed parts and quantity
Switchgear Components FAQ
Short answers for replacement matching, drawing checks and procurement preparation.
How should I choose the right switchgear component group?
Start with the cabinet position and component function, then compare the product photo, drawing dimensions and rating data before sending the RFQ.
Can XIYA match replacement parts from photos?
Yes. Send the old part photo, cabinet or breaker model, nameplate data, mounting dimensions and quantity so the closest route can be checked.
When are drawings required?
Use drawings when outline size, fixing holes, phase spacing, terminal direction or cabinet cutout dimensions must be confirmed.
Why are some accessory groups listed together?
Some accessory groups have enough data for quotation checks but not enough model photos and drawings for a separate model gallery.
Send the part photo, drawing, rating and quantity.
For component replacement, the fastest path is a product photo plus cabinet model or drawing. XIYA POWER can review the match before quoting.
