Legrand MCBs: 1,988 refs, 1-6000 A

There are 1,988 mcbs in the Legrand catalogue. 99% of them carry a rated value in the manufacturer data rather than a name only. Rated current spans 1 A to 6000 A, with breaking capacity from 6 to 50 kA. 1-pole is the most common configuration (672 codes), 4-pole the next (430).

How it splits by current

The 76 order-code families here are too fine a grain to compare one by one, so the table groups them by the rated current that is actually present.

The single busiest band is up to 16 A, holding 502 of the 1,988 references (25%).

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.
