ABB OTP100B3M Enclosed Switch Disconnector

The OTP100B3M is a 3-pole enclosed switch disconnector rated at 80A, housed in a rigid glass-reinforced polycarbonate enclosure with IP65 protection. Built for both indoor and outdoor use, it offers reliable local isolation with a padlockable selector handle and defeatable interlocked cover, suited to the dust and heat conditions typical of UAE outdoor installations.

Key Features

  • 3-pole switch disconnector rated 80A (AC-23A) with fixed neutral and PE terminal for 5-wire system installations
  • IP65-rated glass-reinforced polycarbonate enclosure, UV protected, suitable for outdoor and indoor mounting
  • Padlockable selector handle accommodating up to three padlocks, with defeatable interlocked cover for thermographic inspection
  • Threaded cable entries with knock-out holes for 2 parallel cables plus one control cable, top and bottom
  • Genuine ABB quality — impact-resistant housing rated IK08

Applications

  • Local isolation for HVAC units, pumps, and outdoor machinery in commercial and industrial sites
  • 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

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.
  • 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.
