SCHRACK MCBs: 939 refs, 1-63 A
Shortlisting SCHRACK MCBs comes down to a few attributes. This table puts 939 references from 2 series side by side, so the comparison is on paper.
SCHRACK lists 939 order codes under mcbs. 100% of them carry a rated value in the manufacturer data rather than a name only. Rated current spans 1 A to 63 A, with breaking capacity from 4.5 to 25 kA. 1-pole is the most common configuration (200 codes), 2-pole the next (177).
What the range is built from
Each row is one order-code family rather than one product. The figures are the span actually present in the data, so a gap inside a row means that family does not cover it either.
| Series | References | Rated current | Breaking | Poles |
|---|---|---|---|---|
| BM | 721 | 1-63 A | 4.5-25 kA | 1/2/3 |
| AM | 218 | 1-63 A | 4.5-10 kA | 1/2/3 |
Narrowing it down
Start from the full mcbs listing, which carries every reference with its own parameter table. The filters that actually cut the list:
- Poles first. It is the one attribute that cannot be traded later - a 4-pole device will not do a 3-pole job, and the reverse costs an unused pole.
- Rated current second, as a band. Ratings cluster, so 63 A over 58 A buys nothing and narrows the choice.
- Breaking capacity last. It comes in two or three discrete levels, and the highest is only worth paying for at the point of supply.
Every reference below links to its own page with the manufacturer's original description, so the final check is made against the source text rather than against this summary.
