Siemens MCCBs: 17,671 refs, 16-630 A

This category holds 17,671 mccbs from Siemens. 91% of them carry a rated value in the manufacturer data rather than a name only. Rated current spans 16 A to 630 A, with breaking capacity from 16 to 200 kA. 3-pole is the most common configuration (7,292 codes), 4-pole the next (901).

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.

Where the range is thin

These are current bands where one pole configuration is present and the others are not. If a specification lands in one of them, this manufacturer is not the short answer - the next frame size up, or another brand, will be.

What the order data says

Every one of the 17,671 references states the same lead time, 4-6 weeks. On a range this wide that usually means the supplier quotes it per family rather than per part. Origin is recorded for 7,528 of them, mostly CZ (5,848) and MX (1,670).

Narrowing it down

Start from the full mccbs 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.
