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 300mA sensitivity rating mean?
    300mA RCCBs are sized for fire and equipment protection on larger circuits and sub-mains, not personal shock protection — that requires a 30mA device. A 300mA unit is a common choice as a main incomer or sub-distribution protection device upstream of 30mA final-circuit RCDs.
  • How many poles do I need?
    A 4-pole (4P) RCCB switches all three phases plus neutral together. Use 4P for three-phase supplies or distribution boards where the neutral must also be isolated; 2-pole devices are used for single-phase circuits.
  • 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.
