Circuit breakers, contactors and distribution boards differ by a handful of dense attributes. Where ETIM carries that depth — and where clean structure and filters have to take over.
Take a single circuit-breaker family from one manufacturer. It can fan out into fifty or more articles that look almost identical in the shop — same housing, same brand, same photo — and differ only in three fields: rated current (6, 10, 16, 20, 25, 32 A…), number of poles (1P, 1P+N, 3P, 3P+N) and tripping characteristic (B, C, D). Get those three fields clean and filterable, and the customer finds exactly the breaker they need in seconds. Get them wrong, and they order the wrong article — or leave.
Product data for switchgear and distribution technology is attribute-driven: the value sits in rated current, number of poles and tripping characteristic, not in marketing copy. That is the whole challenge of this sub-category, and it is a different problem from writing good descriptions. This sits under the broader electrical wholesale challenge, right next to industrial supplies and C-parts.
In many categories the differentiator is the description or the image. In switchgear it is the attribute set — and it is dense, technical and unforgiving:
The work here is not writing — it is structuring depth so that thousands of near-identical variants stay distinct and findable. That is a normalization problem, and it is the same consolidate-normalize-enrich job every multi-supplier retailer faces, just pushed to its attribute-heavy extreme.
The electrical trade has a strong classification standard: ETIM. It defines classes and features for electrical products, and for switchgear it is genuinely deep — rated current, poles and tripping characteristic are all defined features, not guesswork. When a supplier delivers a clean ETIM feed, you get structured attributes out of the box. But it is worth being honest about the edges:
| Data layer | What ETIM delivers | Where it stops |
|---|---|---|
| Classification | Defined ETIM class per article type | Nothing for products delivered without an ETIM mapping |
| Core attributes | Rated current, poles, characteristic as typed features | Only as good as the supplier fills them — gaps are common |
| Unit consistency | Feature definitions specify units | Suppliers still deliver mixed formats that need normalizing |
| Sales content | Not the job of a classification | Descriptions, benefit copy, images absent |
| Shop filters | Structured features enable filtering | Mapping features to shop facets is on you |
In short: ETIM gives you the classification skeleton and the core features — a huge head start. What it doesn't give you is guaranteed completeness, unit consistency across suppliers, sales content, or the shop-side filter logic that turns features into facets. That last mile is exactly where the manual work lives.
The throughline is consolidate, normalize, enrich, publish — tuned here for attribute depth rather than prose, and that is exactly what Productbay is built for:
Crucially, Productbay starts where ETIM ends. If your major suppliers already deliver clean ETIM feeds, great — Productbay normalizes them into filterable structure and takes over the accessories, niche brands and own-label products that arrive without a classification at all. For the standards themselves — what ETIM, eCl@ss and GDSN each cover — see the standards explainer. Productbay is built for specialist retailers running multi-supplier, multi-channel catalogs — from mid-sized shops to large chains.
Rated current, poles, tripping characteristic — switchgear stands or falls on filterable attributes. See how Productbay normalizes ETIM depth into clean structure and shop filters in a 30-minute walkthrough.
