🔍 How RCBO Works
Normal Operation:
- Current flows through MCB section
- Current balance monitored by RCCB section
Overload/Short Circuit:
- Thermal or magnetic element trips (MCB function)
Earth Leakage (>30mA):
- Residual current detector trips (RCCB function)
Result: Complete circuit protection in one device
