Automatic Mains Failure Assemblies

A comprehensive range of 4P Automatic Mains Failure Assemblies (AMF) designed for permanent or temporary installations, rated from 100A to 800A. Assemblies change over automatically from Permanent Mains to Stand-by Generator or Alternative Mains should the Permanent Mains fail.

Upon restoration of the Permanent supply, the system can automatically revert to Permanent Mains and halt the stand-by generator after a run down period (where applicable).

Changeover is via electrically and mechanically interlocked contactors and control is via a Deep Sea controller, details of which are available upon request.

Typical applications include process plants where an extended period without power has a high financial cost, to installations in remote locations where overhead lines are vulnerable to extreme weather events.
