Thomson TS 840 Automatic Transfer Switches are perfect for agricultural, telecom, and light industrial applications. These switches employ two mechanically interlocked power switching units with a microprocessor based controller to automatically start a generator and transfer system load to a generator supply in the event of a utility supply failure. System load is then automatically retransferred back to the utility supply following restoration of the utility power source to within normal operating limits. The TS840 transfer switch provides an “Open Transition” (i.e. “break-before make”) transfer system with neutral position delay to ensure adequate voltage decay to prevent out of phase transfers. Not Service Entrance Rated - requires a main circuit breaker or manual disconnect switch.
