A Legrand RCBO (Residual Current Breaker with Overcurrent) is a protective electrical device that combines the functions of:
1. MCB (Miniature Circuit Breaker) – protects against overcurrent, including both overload and short-circuit.
2. RCD (Residual Current Device) – protects against earth leakage currents, which can cause electric shocks or fires.

Key Features of a Legrand RCBO:
Dual protection: Against overcurrent and earth leakage.
Compact design: Ideal for residential, commercial, and light industrial installations.
Single-module or double-module options: Depending on the model.
Breaking capacity: Typically 6kA or 10kA.
Tripping sensitivity: Commonly 30mA (for personal protection), but other ratings like 100mA or 300mA are available.
Rated current: Available in various ratings (e.g., 6A, 10A, 16A, 20A, 32A, 40A).
Pole configuration: Usually 1P+N for single-phase systems.
Application:
Legrand RCBOs are commonly used in distribution boards for final circuits where both overload and leakage protection are needed—like bathroom outlets, kitchen circuits, or outdoor installations.
