You would need a primary injection set or a decent MCCB/Breaker tester to fully test a MCB with any accuracy, and as someone has already pointed out, they DON'T come cheap!!
Have a look in ''Test Meter'' product range, you'll probably find one or two lurking around in there.
We use the Megger PCITS 3000-2 (comes in 2 sections) to test our ACB/GCB's's and current relays etc, and that cost around £10K 6 or so years ago. We made up our own current test leads, or you'll be paying something like £1.5K per lead (£3k for both)!! Expensive business what, but you will get 5% discount from our sponsor!! lol!!
So best policy is, if you suspect a malfunctioning MCB, replace it with a new one for the cost of a few quid, you know it makes sense!!.... lol!!
