How we check information
Every manufacturer and equipment page is built from the maker’s own publications and public records, and each page lists its sources with the date they were checked.
Where the facts come from
Company facts, model data and product scope come from the manufacturer’s website and catalogue pages, and from public records such as standards listings, trade-fair lists and government registers where they add something a buyer can use. Each fact carries a numbered reference to the source list at the foot of the page.
How to use the specifications
Values are shown as the manufacturer publishes them. A series range describes the family, so pick the exact model and configuration you need and ask the manufacturer to quote against it. Confirm the supply voltage, duty rating, accessories and documents for your order in writing before purchasing.
Images
Manufacturer photographs appear only with permission. Category images are illustrations of the equipment type and are labelled as such.
Corrections
If a detail has changed, send a correction through the contact form with the page address. Corrections are checked against the manufacturer’s current publications and the page date is updated.
