3 or 30-Cycle Rated Single- or Dual-Operator Nonautomatic Transfer Switches

Russelectric RTS-03 (3 cycle rated) and RTS-30 (30 cycle rated) Series nonautomatic transfer switches are ideal for applications in which immediate restoration of service is not critical, and local maintenance personnel are available to initiate transfer. The nonautomatic transfer switch is a UL-listed double-throw device with identical withstand ratings and design characteristics to RTS Series (low voltage) automatic transfer switches.

Since these nonautomatic switches are identical in design to Russelectric RTS Series (low voltage) automatic transfer switches and of the same exceptional quality, users can be confident that they are time-tested, reliable, and safe.

Maintenance personnel can initiate a source transfer using local electrically operated pushbuttons, an external operator, or remotely (optional).

All nonautomatic switches can be easily converted to fully automatic operation with the addition of a control panel and minor wiring changes. This ensures flexibility for future expansion and system redesign.

Tested, Listed, and Labeled by UL under UL-1008

Before Underwriters Laboratories, Inc. will allow a transfer switch to be listed with a short circuit rating, it requires that the switch be able to close in on the same amount of fault current as it can withstand. All Russelectric RTS Series transfer switches have been fully tested, listed, and labeled for 3-cycle and 30-cycle closing and withstand ratings under UL-1008.

In applications where extremely high short circuit current is available, fuse protection is mandatory. When coordinated with current limiting fuses, Russelectric RTS Series transfer switches have UL-listed closing and withstand ratings of 200,000 A.
