The ABB MD40F3 40A 3P 750V Safety Switch is your reliable solution for safe equipment disconnect and isolation at the point of use. Built for retrofit projects and maintenance planning, this switch helps you keep critical part numbers consistent while upgrading or servicing essential machinery.

Why the MD40F3 stands out

  • Fusible and Non-Fusible configurations in one part number — choose integrated overcurrent protection when needed, or a simple, blow-open isolation switch for maintenance access.
  • 3-pole design supports balanced, three-phase power distribution, ensuring clean, predictable disconnection across all lines.
  • 750V voltage rating makes it suitable for industrial power environments, delivering dependable performance under demanding loads.
  • 40 A current rating covers a wide range of motors, pumps, conveyors, and other equipment common in manufacturing and processing facilities.
  • Part number consistency simplifies inventory and maintenance planning, reducing order errors during retrofits or replacements.
  • Accessible from AmpState with support to verify fit and compatibility, so you can buy with confidence.

Ideal applications and scenarios

  • Equipment disconnects for motors, fans, or pumps during scheduled maintenance or emergency servicing.
  • Point-of-use isolation in control panels, switchgear upgrades, or safety interlock projects.
  • Retrofit projects where keeping the MD40F3 part number streamlines ordering, spare parts, and downtime planning.

What to know before you buy

  • Decide between the fusible option (for in-line protection with compatible fuses) or the non-fusible option (for straightforward isolation without integrated fusing).
  • Ensure the installation matches a 3-pole, 40 A, 750V configuration to align with your circuit design and safety requirements.
  • If you’re unsure about compatibility, AmpState offers guidance to confirm fit and reduce the risk of misorders.
