ABB OT1600E03P 3-Pole 1600A Switch Disconnector

The OT1600E03P is a heavy-duty 3-pole switch disconnector rated at 1600A, complete with a black IP65-rated handle and shaft plus terminal bolt kit for straightforward installation. Built for main isolation duty in high-current distribution systems, it is well suited to large commercial and industrial switchboards, substations, and main incomer applications across the UAE.

Key Features

  • 3-pole switch disconnector rated 1600A (AC-21A/AC-22A) with 1250A rating for AC-23A motor-type loads
  • Black IP65-rated handle and shaft included, along with terminal bolt kit for fast, complete installation
  • 110kA rated short-circuit making capacity (Icm) and 50kA short-time withstand current for demanding fault conditions
  • 1000V rated insulation voltage and 12kV rated impulse withstand voltage for high dielectric strength
  • Genuine ABB quality โ€” manufactured in Finland to IEC 60947-3 standards

Applications

  • Main incomer isolation in large low voltage switchboards and substations
  • High-current load isolation for major feeders in industrial facilities
  • Main disconnect switching in generator and transformer-fed distribution systems
  • Safe isolation point for maintenance on high-capacity electrical infrastructure in UAE facilities

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.
