MCBs cross-reference 7 brands: 12,325 refs
MCBs from 7 manufacturers side by side: reference counts, current and breaking ranges, and where the published specifications do not line up.
7 manufacturers in this catalogue publish mcbs, 12,325 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
| Brand | References | Rated current | Breaking | Poles |
|---|---|---|---|---|
| eaton | 4,157 | 0.5-100 A | - | 1/3 |
| siemens | 2,210 | 0.3-100 A | 4.5-25 kA | 1/3 |
| legrand | 1,988 | 1-6000 A | 6-50 kA | 1/4 |
| hager | 1,593 | 0.5-125 A | 3-50 kA | 1/3 |
| schrack | 939 | 1-63 A | 4.5-25 kA | 1/2 |
| allen-bradley | 843 | 0.5-63 A | - | - |
| gewiss | 595 | 1-125 A | - | 1/2 |
Where the ranges differ
- The widest current coverage is legrand, up to 6000 A; the narrowest is schrack at 63 A.
- eaton, allen-bradley, gewiss 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.
