Open-Transition Transfer, Closed-Transition Retransfer and Testing
Russelectric® RTS Series closed-transition bypass/isolation switches combine a closed-transition automatic transfer switch with a manually operated bypass switch. They allow the open-transition transfer of electrical loads from a preferred power source to an alternate power source when voltage and/or frequency varies from preset limits, and the closed transition retransfer of loads when the preferred source is restored. In addition, they offer the advantage of zero power interruption during testing.
Built to the same stringent standards as Russelectric’s widely respected break-before-make switches, they are identical in size to RTS Series open-transition switches.
Russelectric Closed-Transition 30-Cycle Bypass/Isolation Switches are available in the following versions:
