Changeover 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,…

Manual Changeover Switch Assemblies (MCO) are designed for permanent and temporary installations, to switch from a permanent mains supply to a stand-by generator (or alternative mains supply) should the permanent mains fail. Upon restoration of the permanent supply, the switch can be manually changed back to permanent mains power. They are a simple, cost effective method of providing back-up power to installations where a loss of supply for a short duration is acceptable.

When an installation is to be provided with a stand-by generator, if quick connection is required, a Generator Connection Point (GCP) should be installed. GCPs incorporate single-pole drain power connectors rated at 500A or 800A, which mate with suitable cable mounted single-pole source connectors fed from the generator. To provide greater security against accidental or unauthorised withdrawal or insertion of connectors, the powerlock connectors are mounted behind a padlockable door which provides controlled access.
