Automatic Transfer Assemblies

A comprehensive range of 4P Automatic Transfer Switch Assemblies (ATS) designed for permanent installations, rated from 60A to 400A. 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 Life Safety Systems where critical parts of an installation require back-up power.
