How to Match Copper / VS1 / ZN85 Contact Arm
Use the model cards for visual matching, then confirm the cabinet position and rating details before sending the RFQ.
Confirm where the part sits
Primary current path on VCB drawout trucks, fixed connection points and VS1 or ZN85 contact systems.
Compare the interface
Compare arm length, contact diameter, threaded hole, tulip contact interface and silver-plated contact area.
Do not match by shape alone
Current rating, contact pressure and breaker truck series must match. Similar copper profiles can belong to different current paths.
Drawing and data boundary
Use drawings for dimensions, not for rating assumptions.
Use product photos for contact-end matching and drawings for length, hole depth and thread confirmation.
- 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.
Copper / VS1 / ZN85 Contact Arm Selection FAQ
Short answers for replacement matching and procurement checks.
How should I match Copper / VS1 / ZN85 Contact Arm for replacement?
Start with the installed cabinet position, then use the product photo and drawing to check: Compare arm length, contact diameter, threaded hole, tulip contact interface and silver-plated contact area.
Can similar Copper / VS1 / ZN85 Contact Arm shapes be used interchangeably?
Current rating, contact pressure and breaker truck series must match. Similar copper profiles can belong to different current paths.
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.
Contact Box
Use for epoxy contact boxes, fixed contact openings and VCB truck contact interfaces.
Fixed Contact, Tulip Contact and Flat Contact
Use for fixed contacts, tulip contacts and flat contacts that must match the copper arm interface.
Vacuum Pole Assembly / VS1 Insulated Cylinder
Use for embedded poles, insulated cylinders and VS1 breaker service positions.
Send the cabinet model, rating, drawing and quantity.
For replacement selection, include an old part photo, cabinet type, voltage class, mounting dimensions and quantity.
