The limitation capability of an MCB is an internal characteristic which makes it possible to open the circuit before the short circuit current reaches its prospective maximum value.

An MCB with a better current limitation capability provides several advantages

• To reduce the thermal effects in the cable i.e. increase life span of cables.
• To reduce the mechanical effects and electrodynamics forces on the different contacts.
• To reduce the electromagnetic effects which can be harmful to sensitive equipment / loads.
