Thompson Technology TS 840 Series Automatic Transfer Switch: 100- 800 Amp

Thomson Technology TS 840 series of Automatic Transfer Switches (ATS) employ two mechanically interlocked enclosed contact power switching units and a microprocessor based controller to automatically transfer system load to a generator supply in the event of a utility supply failure. System load is automatically re-transferred back to the utility supply following restoration of the utility power source to within normal operating limits. Thomson Technology TS 840 Service Entrance Automatic Transfer Switches incorporate an isolating mechanism and over current protection on the utility supply thereby removing the need to have a separate, upstream circuit breaker/disconnect switch from the transfer switch. This unique Service Entrance Rated Automatic Transfer Switch design is incorporated into a standard sized automatic transfer switch enclosure providing a space saving, cost effective solution for most applications.
