FAQ

  • What's the difference between an MCB and an RCCB/RCD?
    An MCB (Miniature Circuit Breaker) protects a circuit against overload and short-circuit faults. An RCCB (Residual Current Circuit Breaker), also known as an ELCB, continuously monitors for earth leakage current and disconnects the supply if current is escaping to earth – protecting against electric shock and fire in a way an MCB cannot.
  • What does the 30mA sensitivity rating mean?
    30mA is the internationally recognised threshold for personnel protection against electric shock, making the CDC226J suitable for final circuits – sockets, lighting, and general power – where there is direct risk of human contact.
  • How many poles do I need for this circuit?
    This is a 2-pole (2P, 1P+N) device switching both line and neutral, suited to single-phase circuits. Three-phase circuits require a 4-pole equivalent.
  • Can I install this myself?
    No. This is a distribution-board-mounted device and must be installed and connected by a licensed electrician in accordance with UAE wiring regulations.
  • What is Onekonekt?
    Onekonekt is Hager's unified range of modular protection devices – MCBs, RCCBs, RCBOs, and main switches – designed to fit a common single- or three-phase busbar system with BIconnect terminals, so devices can be wired from cables or fed directly from the busbar, speeding up panel-building and reducing wiring errors.
