Contactors cross-reference 10 brands: 13,213 refs

10 manufacturers in this catalogue publish contactors, 13,213 references in total. The ranges overlap far less than the category name suggests - below is what each one actually covers, taken from their own order data rather than from a catalogue cover.

What each brand actually lists

Where the ranges differ

• The widest current coverage is abb, up to 2650 A; the narrowest is hager at 160 A.
• siemens, allen-bradley, eaton list no breaking capacity in the source data at all - not a gap in the range, a gap in the published specification, which matters when you are comparing on paper.

Choosing between them

The brand is rarely the deciding variable. In practice the order is: the current band and pole count your protection study calls for, then the breaking capacity at the point of supply, then what is on the shelf. Only when two candidates tie on all three does the manufacturer matter.
