The MCB — often called a miniature "aptomat" or automatic breaker in Vietnam — protects branch circuits against overload and short circuit and is mounted on a DIN rail inside the panel. It is one of the most frequently purchased switching devices, for both household installations and factory distribution boards.
Select on four parameters: number of poles (1P for single-phase circuits, 2P when the neutral must also be disconnected, 3P for three-phase loads), rated current according to the load current and conductor cross-section, breaking capacity of 6 kA or 10 kA according to the position in the system, and tripping curve (curve C is the default for mixed loads). Close to the main switchboard choose 10 kA; for final branch circuits 6 kA is usually sufficient.

Number of poles37 items without data
1-pole and 2-pole devices are used on single-phase circuits and can also be used on three-phase 4-wire circuits; 3-pole devices on three-phase 3-wire or 4-wire circuits; 4-pole devices on three-phase 4-wire circuits (IEC 60898-1, Table 1).
Rated current In, A37 items without data
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 kA97 items without data
Rated short-circuit breaking capacity of an MCB under IEC 60898-1, symbol Icn; industrial circuit-breakers under IEC 60947-2 state Icu. The value is always given together with a 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).
