How to Match Sensor / Instrument Transformer Accessories
Use the model cards for visual matching, then confirm the cabinet position and rating details before sending the RFQ.
Confirm where the part sits
Metering feedback, CT accessory and sensor support positions inside switchgear bays.
Compare the interface
Compare mounting base, cable exit, sensing aperture, insulation body shape and terminal position.
Do not match by shape alone
Confirm the actual CT or sensor rating from the nameplate and circuit document. Accessory shape alone cannot define the metering ratio.
Drawing and data boundary
Use drawings for dimensions, not for rating assumptions.
Where a matching drawing is not available, send a product photo, nameplate photo and mounting sketch with the RFQ.
- Check outline dimensions, fixing holes and interface direction.
- Confirm voltage class, current rating and cabinet series from actual project data.
- Send an old part photo and cabinet nameplate when replacing installed components.
Sensor / Instrument Transformer Accessories Selection FAQ
Short answers for replacement matching and procurement checks.
How should I match Sensor / Instrument Transformer Accessories for replacement?
Start with the installed cabinet position, then use the product photo and drawing to check: Compare mounting base, cable exit, sensing aperture, insulation body shape and terminal position.
Can similar Sensor / Instrument Transformer Accessories shapes be used interchangeably?
Confirm the actual CT or sensor rating from the nameplate and circuit document. Accessory shape alone cannot define the metering ratio.
What should be included in the RFQ?
Send the old part photo, cabinet model, voltage class, rating, mounting dimensions, quantity and any available drawing.
Related Component Types
Check adjacent component types when the same cabinet position includes insulation, contact, control or breaker service parts.
Secondary Plug Connector
Use for secondary plug interfaces, control wiring connection points and interlock signal circuits.
Contact Box
Use for epoxy contact boxes, fixed contact openings and VCB truck contact interfaces.
Wall Bushing
Use for busbar or cable-side wall passages where flange, cutout and conductor centerline must match.
Send the cabinet model, rating, drawing and quantity.
For replacement selection, include an old part photo, cabinet type, voltage class, mounting dimensions and quantity.
