The MCCB, commonly called a moulded-case "aptomat" or moulded-case CB, is used for high-current circuits that an MCB cannot handle: main switchboards, power feeders from the transformer substation, and incomers to area distribution boards. It has a moulded case and is screwed to the panel mounting plate rather than clipped onto a rail like an MCB.
Besides the rated current, the decisive parameter is the breaking capacity Icu — the highest short-circuit current the device can break, which must always be stated together with the voltage. Many MCCB ranges have an adjustable trip setting, allowing on-site adjustment to the actual load instead of replacing the whole device.

The current declared by the manufacturer for the circuit-breaker under the stated operating conditions. Choose In not less than the design current of the circuit and not greater than the permissible current of the conductor (QCVN 12:2014/BXD, clause 2.6.3.1).
Breaking capacity Icu, kA126 items without data
The short-circuit current the circuit-breaker can break at a stated voltage, so catalogues give it together with the voltage. Choose a breaking capacity not less than the prospective short-circuit current at the point of installation (QCVN 12:2014/BXD, clause 2.6.5.4).
