Automatic Transfer Switches (ATS)

Automatic Transfer Switches (ATS) are essential wherever substantial power has to be maintained. Whether it's to ensure peoples safety in a work or public space, or to maintain essential supplies to a vital process, the fast and efficient transfer of power is automatically managed by the ATS system.The second source of power can either be from a generator or from an alternative/stand-by source. Either of which can be accommodated in Craig & Derricott's range of ATS systems.

At the core of each system is a three/four pole changeover device. The 'Standard' range utilises electromechanical contactors whilst the 'Advanced' range uses two load break isolators.

Two distinct ranges are available to cover differing requirements :-

The 'Standard Range' provides all of the essential requirements for automatically providing a replacement power source. Facilities are provided to control the start of standby generators manually and to set the undervoltage values and the required time delay. Neon lights are provided to show the status of the supplies.

The 'Advanced Range' provides a more comprehensive control system where the user has an extensive set of variables under their control.

Full details of both ranges can be found in our 'i-switch' catalogue (Pages 23-25, 30)  - i-switch catalogue
