Features Surge Diverter Series

1 Surges and voltage transients are a major cause of expensive electronic equipmentfailure and business disruption. Damage may result in the loss of capital outlays,such as computers and communications equipment, as well as consequential loss of revenue and profits due to unscheduled system TDS Series of Surge suppressors provide economical and reliable protectionfrom voltage transients on power distribution systems. They are conveniently packaged for easy installation on 35 mm DIN rail within main distribution TD technology helps ensure reliable and continued operation during sustained and abnormal over-voltage events. Internal thermal disconnect deviceshelp ensure safe or at end-of-life. A visual indicator flag provides user-feedback inthe event of such operation. As standard, the TDS provides a set of voltage-freecontacts for remote signaling that maintenance is convenient plug-in module, and separate base design.
