Craig & Derricott introduce a new design to their range of Automatic Transfer Switches



Automatic Transfer Switches (ATS) are essential wherever substantial power must be maintained. Whether it’s to ensure people’s 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. Craig & Derricott has always designed their ATS units to be operational in a variety of installations such as hospitals, water distribution facilities, airports, banking computers, data centres, shopping centres, offices, apartments and railway – wherever there is a critical need for the automatic transfer of power from permanent (S1) to an alternative (S2) supply.

Over the last 6 months, Craig & Derricott has re-developed their range of Automatic Transfer Switches and can now offer this new design to the market.

At the core of each system is a four-pole contactor changeover device. Rated 230V or 400V AC the range utilises electromechanical interlocked 4 pole AC1 / AC3 rated contactors and provides all the essential requirements for automatically switching to a replacement power source. Units are rated from 32A to 800A with a rated frequency of 50 / 60Hz.
