Prevention of hazards and damage (such as electrical shock, electrical fire, and device damage)
that may occur in electrical equipment (as stipulated in IEC 60364)
A. Protection against direct contactProtection of people from harzards(i.e.,electrical shock) that may occur due to touching charged parts of electrical equipment. |
B. Protection against indirect contactProtection of people from electrical shock that may occur due to touching exposed conductive parts( such as metal frame of the device) when a fault occurs in electrical equipment. |

MCB is a miniature circuit breaker which is used to break small currents.(Like in domestic LT circuits)
* The ratings usually end up to 100 A
* Interrupting rating of under 18000 A
* Trip characteristics may not be adjusted
* Suitable for low current circuits (low energy requirement), i.e. home wiring.
* Generally, use where normal current is less than 100 A
MCCB is a molded case circuit breaker which has a rugged construction as it can break
Larger currents usually from (100~1000 A)
* Rated current in the range of 10-2500 A
* Thermal operated for overload and Magnetic operation for instant trip in SC(Short Circuit conditions)
* Interrupting rate can be around 10k~200k amps
* Suitable for high power rating and high energy i.e. commercial and industrial use
* Generally, use where normal current is more than 100 A
