A DIN-rail modular socket is a service interface inside a panel, not automatically a protective device. Selection should match the feeding circuit, socket standard, mounting format, enclosure access and intended user. The panel drawing must also state whether the outlet remains live when the main isolator is open.
What is the socket expected to supply?
Define whether it is for commissioning, maintenance tools, a temporary service supply or an equipment connection. Then identify voltage, current, frequency, contact arrangement, plug standard and the circuit protection assigned upstream. The CQP20 modular socket range is a model-review starting point, not evidence that every variant suits every market.
Which rail and enclosure dimensions must be confirmed?
Check modular width, rail type, depth, terminal access, adjacent-device clearance and the method of replacement. Do not infer these details from a product photo. They belong in the assembly drawing and the selected model’s installation instructions.
How should the socket circuit be described?
State the supply system, rated voltage, intended load and protective device. A socket being mounted on DIN rail does not provide overload or residual-current protection by itself. Verify the applicable socket standard and local installation rules for the destination market.
When do shutters, adapters and service access matter?
List shutters, covers, adapters, earth continuity, mechanical retention and labeling as separate requirements. If the outlet is fed from an independent circuit, identify that source clearly so maintenance personnel do not assume that opening the main isolator makes the socket dead.
What should a buyer request from the supplier?
Send the plug standard, voltage and current, mounting format, protection arrangement, enclosure conditions, accessory list, quantity and required documentation. A clear schedule lets the supplier return a specific model instead of a generic modular-socket catalogue.
Which CHAC product route should be reviewed first?
Review the CQP20 page and related modular connection accessories against the panel schedule. Keep outlet selection separate from the MCB or RCCB decision so each protective function remains traceable.
When should the socket schedule be frozen?
Freeze it after the circuit role, rail space, supply source, protection and access procedure are approved. If the socket remains energized during maintenance, make that condition visible in the panel documentation and safety procedure.
الختام DIN-rail service socket entry should identify the supply source, protective device, plug standard and whether the outlet remains live during panel isolation.

الأسئلة المتكررة
Is a DIN-rail socket a protective device?
No. It is an outlet interface unless the project design documents a different verified function.
Can mounting be inferred from a product photo?
No. Confirm modular width, rail type, and enclosure clearance from the assembly drawing.
What voltage information belongs in the RFQ?
State the feeding circuit voltage and any interface constraints required by the selected socket documentation.
Why list accessories separately?
Shutters, adapters, and companion modules are model-specific and should not be assumed from a category page.
What should the supplier return?
Proposed model identification and the documents requested for terminals, mounting, and ratings evidence.
When should the socket schedule be frozen?
Freeze it after rail space and circuit role are approved, before the panel bill of materials is released.
