• Safe isolation point for maintenance on rooftop and plant room equipment
• Feeder isolation in FM-managed facilities requiring IP65-rated enclosures

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 — 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 — an isolator is not a protective device and should not substitute for a circuit breaker.
