FAQ

• What's the difference between an MCB and an RCCB/RCD?
  An MCB protects circuits and wiring against overload and short-circuit current. An RCCB like this one protects against earth leakage by monitoring current imbalance and disconnecting the circuit — the two are complementary and are normally installed together in a distribution board.
• What does the 30mA sensitivity rating mean?
  30mA RCCBs are sized for personnel/shock protection on final circuits — the standard choice for socket outlets and circuits people directly touch.
• How many poles do I need?
  A 2-pole (2P) RCCB switches live and neutral on a single-phase circuit.
• Can this be used alongside MCBs in the same board?
  Yes. This RCCB is typically installed upstream of the MCBs it protects, on the same DIN rail, so a leakage fault trips the RCCB while overloads/short circuits are still cleared by the individual MCBs.
• Can I install this myself?
  No. RCCBs are wired into a live distribution board and must be installed by a licensed electrician in line with UAE wiring regulations.
