Applications

  • Local isolation for HVAC units, pumps, and outdoor machinery requiring remote status feedback
  • Main isolation switch for external distribution boards exposed to UAE outdoor conditions
  • Safe isolation point for maintenance on rooftop and plant room equipment
  • Feeder isolation in FM-managed facilities requiring IP65-rated enclosures with auxiliary signaling

FAQ

  • Is this an MCB or an isolator?
    It's an isolator (switch-disconnector), not an MCB. It has no overload or short-circuit protection โ€” it only provides a manual on/off disconnect, and should be paired with separate MCBs or RCCBs for circuit protection.
  • What does 3-pole mean for this isolator?
    3-pole means it switches all three phases on a three-phase supply.
  • Where should this isolator be installed?
    Typically as the main incoming switch or a local isolation point ahead of the MCBs/RCCBs in a distribution board, so the whole board (or a section of it) can be isolated for maintenance without needing to trip individual breakers.
  • Can I install this myself?
    No. This is trade-only distribution board equipment and must be installed and connected by a licensed electrician in accordance with local wiring regulations.
  • Can this isolator be used to switch a live circuit under load?
    Isolators rated for on-load switching can do this within their utilisation category, but check the specific AC rating in the Technical Specifications table โ€” an isolator is not a protective device and should not substitute for a circuit breaker.
