Switchgear and protective devices.

This group determines the safety of the entire electrical system: the MCB protects branch circuits against overload and short circuit, the MCCB protects high-current circuits, the RCCB and RCBO provide residual current protection for people, fuses clear short-circuit faults quickly, and the ATS transfers the supply when mains power is lost. Many people in Vietnam still call them all "aptomat", but each type has its own function and they are not interchangeable.

Two figures must match when selecting: the rated current must suit the operating current and the conductor cross-section, and the breaking capacity must exceed the calculated short-circuit current at the point of installation. With insufficient breaking capacity, the device fails at the first fault and cannot interrupt it. Hoang Nhat distributes Sino, Panasonic and Chint for MCB/MCCB/RCCB, and Thivico and Giga for fuses and disconnectors.
