Allen-Bradley MCBs: 843 refs, 0.5-63 A

There are 843 mcbs in the Allen-Bradley catalogue. 90% of them carry a rated value in the manufacturer data rather than a name only. Rated current spans 0.5 A to 63 A.

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.

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:

• The rating that cannot be traded off. Every family has one - the figure the application is built around - and it decides the rest.
• The physical envelope second. It is what the panel or the machine has to accommodate, and it is expensive to change later.
• Availability last. Between two parts that both fit, the one with a stated lead time is the one to quote.

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.
