Compressor connector durability should be reviewed against start-stop duty and the complete contact system, not inferred from a housing image or a generic cycle count. Keep mating, harness movement, appliance conditions, and evidence tied to the released revision.

• Part 3. Include harness and appliance conditions
• Part 4. Record wear evidence carefully
• Part 5. Build the application RFQ

Part 1. Define start-stop duty

State the intended start-stop pattern, review objective, and configuration. A cycle term without a defined duty boundary cannot establish an application conclusion.

Part 2. Identify contact and mating inputs

Record connector, mating part, contact arrangement, housing, keying, and revision. Similar-looking contacts do not establish interchangeability or life.

Important: Do not treat a product image or generic cycle statement as proof of contact durability. Source: IEC.

Part 3. Include harness and appliance conditions

Record movement, support, routing, enclosure, temperature or moisture boundary, and the appliance context that belongs to the inquiry.

Part 4. Record wear evidence carefully

Ask which configuration and conditions an observation covers. Keep wear observations separate from a life promise or a conclusion about an unlisted appliance.

Part 5. Build the application RFQ

RFQ field	Provide	Purpose
Connection	Connector, mating, contact, housing, revision	Identify the system
Duty	Start-stop boundary and appliance conditions	Define the application
Movement	Harness route, support, and access	Preserve installed context
Evidence	Sample objective, records, open questions	Make review traceable
## Part 6. Control alternates and use a ZUCH inquiry
Reopen review after a contact, housing, route, duty, or requirement change. Use the ZUCH appliance solution route for application discussion and the sample request route for controlled inputs. The motor connector vibration-retention checklist offers a separate evidence lens.
## FAQ
### Does a cycle count prove durability?
No. The configuration, duty, conditions, and evidence boundary must be identified.
### Which contact inputs matter?
Identify the contact arrangement, mating part, housing, keying, and revision.
### Why include harness movement?
It keeps the review tied to the installed appliance rather than a loose sample.
### Can a product image prove contact wear life?
No. An image is discovery context, not durability evidence.
### When should review be repeated?
Repeat it after a configuration, duty, environment, or evidence-scope change.
### What belongs in the RFQ?
Send drawings and revision, duty, appliance conditions, harness movement, sample objective, evidence request, and change control.
