There can be confusion around why a given part has two different voltage or current ratings, especially when these ratings don’t match between a product page, an invoice, a description, or sometimes what is physically printed on the part which may cause question if you received the correct part.
A given part may have two or more approval ratings, each approval rating will have their own testing parameters, which will lead to various maximum recommended ratings. Sometimes a product page will list 30A but the received product description may only list 16A.
Taking for example fuse block 283-2938-ND, a customer may assume they are ordering a 600V 30A product based on a description or some other piece of literature, but when the part is actually received may only show 300V 16A on the product or description, both of which are true in their own right.
The actual product has these ratings which are commonly found in the datasheet:
UL: 600V 30A
CSA: 300V 16A
- The important aspect to note is which rating does your project need to meet for its qualifications?
- Does it need to be UL or CSA certified?
Tech Tip: This is one example, but these various approval ratings can apply to all kinds of components such as switches and many other products. The best place to locate facts is the product datasheet, or the series catalogue. Keep in mind there may be revisions or updates to these documents as the parts or their testing qualifications may be subject to change.
