Working of fuse
Introduction to mcb
Parts of mcb
Difference between mcb and fuse
This kind of fuse is most commonly used in the case of domestic wiring and small scale usage. Another name for this type is the KIT-KAT type fuse. The main composition is of a porcelain base which holds the wires.
The main advantage of this type of fuse is that it is easy to install and also replace without risking any electrical injury.
When there is an over surge that causes the fuse element to blow off, you can replace it. A new fuse carrier is inserted in the base.
Link type fuses: In Link type, we further have a knife blade type and a bolted type.
D Type Fuses: This cannot be interchanged and comes with the following main components: fuse base and cap, adapter ring and the cartridge.
Miniature circuit = switch + trip unit breaker (MCB)
NC100 / NC125

The magnetic trip unit is comprised of an electromagnet and an armature. When there is a short circuit, a high magnitude of current passes through the coils creating a magnetic field that attracts the movable armature towards the fixed armature. The hammer trip is pushed against the movable contact and the contacts are opened. The opening of the breakers contacts during a short circuit is complete in .5 milli-seconds.
