Automatic Mains Failure and Manual Changeover Assemblies
A comprehensive range of 4P Automatic Mains Failure Assemblies (AMF) designed for temporary installations, rated from 100A to 800A. Assemblies change over automatically from mains to stand-by generator or alternative mains should the mains fail.
Manual Changeover Switch Assemblies (MCO), rated from 100A to 630A, are designed for temporary installations, to switch from a mains supply to a stand-by generator (or alternative mains supply) should the mains fail. Upon restoration of the mains supply, the switch can be manually changed back to mains power. They are a simple, cost effective way of providing back-up power to an installation.
For free standing applications we offer a range of purpose built stands and crash frames.
