What is the difference between an MCB, an RCCB and an RCBO?

An MCB protects against overload and short circuit (overcurrent). An RCCB protects against earth leakage and electric shock by detecting current imbalance, typically at 30mA, but offers no overcurrent protection. An RCBO combines both functions in one module, giving overcurrent and earth-leakage protection per circuit, saving DIN-rail space.

Should I use a Type AC or Type A RCCB in India?

Type AC detects only AC earth leakage and suits basic resistive and inductive loads. Type A also detects pulsating DC leakage produced by electronics, EV chargers, inverters and LED drivers. Since most Indian homes now run such loads, Type A is the safer choice. Use Type B for solar inverters and variable-frequency drives.

What breaking capacity (kA) do I need for an Indian home?

Breaking capacity is the maximum fault current an MCB can safely interrupt. For most homes located some distance from the transformer, 6kA is adequate. For apartments, boards close to the distribution transformer, and commercial mains, specify 10kA or higher. Always base it on the actual prospective short-circuit current at your board.
