FAQ
-
What is an RCBO, and how is it different from an MCB or RCCB?
An RCBO (Residual Current Breaker with Overcurrent protection) combines an MCB and an RCCB in one device — it protects a single circuit against both overload/short-circuit and earth leakage, instead of needing separate devices.
-
What does the 100mA sensitivity rating mean?
100mA RCBOs are sized for fire and equipment protection rather than personal shock protection, which requires 30mA.
-
Why use an RCBO instead of a shared RCCB for multiple circuits?
An RCBO protects one circuit only, so a leakage fault on that circuit trips just that RCBO rather than a shared RCCB covering several circuits — this avoids losing power to unaffected circuits when a fault occurs on one.
-
Can I install this myself?
No. RCBOs are wired into a live distribution board and must be installed by a licensed electrician in line with UAE wiring regulations.
