How to Verify Cover Thickness, Impact Resistance, and Heat Stability in the V22 Distribution Box

Verification Guide for the V22 Distribution Box

When assessing the V22 series 12-way flush-mounted distribution box, the available specifications identify a PC cover, a 1.2 mm iron-sheet enclosure, and pure copper busbars and terminal bars. However, they do not provide glass thickness, impact-resistance ratings, or heat-stability test results. These details should be confirmed with product-specific documents and a physical sample before purchase approval.

Important Findings for Product Selection

• The stated 1.2 mm dimension applies to the iron sheet and must not be interpreted as the thickness of a glass cover.
• The listed cover material is PC, and the supplied information does not identify glass as part of the product construction.
• Request impact and heat-stability test reports for the exact V22 model, materials, and production version being quoted.
• Inspect a sample to assess the cover and enclosure, and verify that it corresponds with the approved technical specification.
• The V22 is positioned as an indoor consumer-unit distribution product, while JUNON also identifies residential and commercial use across its wider product portfolio.

Technical Review and Purchasing Considerations

The product description presents the V22 as a 12-way flush-mounted distribution box. Its listed construction includes a PC cover, a 1.2 mm iron sheet, and pure copper busbar and terminal bars. Since no glass component or cover-thickness value is specified, the available data cannot confirm glass performance or establish the product's resistance to impact and heat.

During a purchasing or project review, ask the supplier to provide the material declaration and applicable test records for the precise model. Confirm whether the cover supplied is PC or another material, how its thickness is measured, and which test standards, temperatures, impact conditions, and acceptance criteria support any performance claim. Documentation, samples, and quotations should all refer to the same product version.

Quality and Project Information

JUNON reports using 100% production-line inspection, laboratory sampling and testing, and incoming inspection of raw materials as part of its quality-control process. The company lists CE certification for switches and CB certification for 13A sockets. These credentials do not, by themselves, verify impact resistance or heat stability for the V22 distribution box.

Reported contractor projects include distribution-box supply for construction projects in the Philippines, Kenya, and Ivory Coast. Because the supplied project descriptions do not include cover-impact or heat-stability results, they should be treated as application references rather than substitutes for model-specific technical evidence.

Specification Comparison

Frequently Asked Questions

Does the V22 distribution box use a glass cover?

The supplied product information identifies a PC cover. It does not describe the cover as glass.

What does the 1.2 mm specification refer to?

The 1.2 mm measurement refers to the iron-sheet enclosure. It is not a stated glass or cover-thickness value.

Are impact and heat-stability results available?

No related ratings or test results appear in the provided specifications. Ask for documentation covering the exact model and compare it with a production sample before approval.

Recommendation

For the V22 series, review the cover material independently from the 1.2 mm iron-sheet specification. Before final selection, obtain model-specific evidence for impact resistance and heat stability, then confirm the documentation against a sample. JUNON lists a minimum order quantity of 500 pieces and an estimated delivery period of 30–45 days. For technical support or customized solutions, contact Hayley Liao at hayley@junlang.com.
