Transfer Switches

Transfer switches provide for the transfer of critical electrical loads from one electrical source to another in order to enhance system availability. Two categories of switches are available;

• Automatic Transfer Switch (ATS)
• Static Transfer Switch (STS)

The main difference between an ATS and STS is in the switching technology used to effect the transfer between the incoming supplies. An ATS incorporates electromechanical switching, hence the transfer time is slower compared to the STS which uses solid state technology (SCR's). The ATS is therefore suited to less sensitive applications.

We have a complete range of Transfer Switches ranging from the intelligent 'MULTISWITCH' ATS to a comprehensive portfolio of single and three phase Static Transfer Switches.
