Double-pole switches appear in product schedules for projects that call for a specific switching arrangement. The term describes a product function; it does not by itself establish the correct application, rating or suitability for a particular installation. Buyers should tie the requested function to a model and its current documentation.
Define what the project requires
Record the intended use supplied by the project designer, the control arrangement, mounting format, finish and required faceplate. Do not select a switch from its appearance or a short catalogue name alone.
Confirm model-level details
- Ask for the exact item code and current product datasheet.
- Confirm rated voltage, current and any specified load type from the manufacturer’s documents.
- Review dimensions, terminal details and product drawings with the responsible project professional.
- Check which conformity documents apply to the exact model and destination.
- Approve a labelled sample if the plate layout or finish matters.
Keep market and installation decisions traceable
Requirements vary by country and project. Have the local compliance requirements and installation suitability checked by the project’s qualified electrical professional. Do not treat a catalogue listing or this buyer checklist as installation advice or proof of approval.
OUBEN’s F9 catalogue lists double-pole switch products, including entries described as 20A and 45A. Treat those as catalogue labels only: verify the current ratings, intended functions and market documents for the exact item before shortlisting or publishing a specification.
