Description
IACM load-break disconnector switches are designed for low-load breaking overhead MV
electrical lines.
Equipped with an air-break technology system combined with an isolating switch in series,
this device provides visible opening and great safety in operation.
IACM switches are suitable for overhead distribution networks up to 24 kV, and especially
those requiring a high level of insulation:
• No maintenance required.
• Easy pole top mounting.
• Line works can be carried in safe conditions thanks to the visible opening and high level
of insulation.
• A manual control mechanism is available with a rod assembly and padlockable lever.
• Whip breaking system.
• The IACM switch control mechanisms are equipped with a tumbler spring system which
directly operates the mobile shaft.
The operating speed is not dependant on the operator.
• Height of the pole from 9 to 11 m.
• Synthetic Insulators designed with a central part in epoxy resin. The flexible skirts in over
molded silicone provide an important creepage distance and a good protection against
vandalism.
