Siemens Contactors: 5,424 refs, 7-690 A

There are 5,424 contactors in the Siemens catalogue. 99% of them carry a rated value in the manufacturer data rather than a name only. Rated current spans 7 A to 690 A. 3-pole is the most common configuration (2,215 codes), 4-pole the next (382).

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.

What the order data says

Every one of the 5,424 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 4,568 of them, mostly DE (4,124) and CN (236).

Narrowing it down

Start from the full contactors listing, which carries every reference with its own parameter table. The filters that actually cut the list:

• Power and duty first. Continuous or intermittent duty decides the frame, and frame decides everything downstream.
• Voltage and frequency second. They are fixed by the supply, not by preference, and they eliminate whole families at once.
• Mounting last. Flange, foot or shaft-end is a mechanical constraint, and it is the one item that is genuinely hard to change after installation.

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.
