MCB - Construction Vise

Dear guest,

If you are the same one who has asked the other two questions regarding MCB recently, IMHO you can't learn any product this way using one-liners. You need to learn a substantial amount about MCB before asking questions about small details. For exemple,different curves can be obtained by using different heaters and sometimes, maybe even different bimetals with different flexivity....also magnetic biasing springs, magnet airgaps...so on.

Good luck.

As to construction you will have to look to manufactures sites. For definition look at BS7671

Constrcutional difference is in the guage size and in the number of turns of the magnetic trip coil windings of these MCBs.
