Russelectric, A Siemens Business, Offers RTS-30 Series Automatic Transfer Switches for Water/Waste Treatment Facilities

The most complete line of rugged 480 VAC 30-cycle and 3-cycle UL tested switches available

Hingham, MA - Russelectric, A Siemens Business, a leading manufacturer of power control systems and automatic transfer switches, announces the Russelectric RTS-30 Series of automatic transfer switches for water/waste treatment and other critical facilities, the most rugged and complete line of 480 VAC 30-cycle and 3-cycle UL tested switches available in the market today. All Russelectric RTS-30 Series automatic transfer switches have been fully tested, listed, and labeled for 30-cycle and 3-cycle closing and withstand ratings under UL-1008.

The RTS-30 Series of transfer switches feature preloaded springs and an over-center mechanism driven by an electric operator for opening and closing the power contacts. During an open-transition transfer, the contact mechanism is securely locked in position until the over-center position is reached. The preloaded springs then instantaneously open the closed contacts (quick-break) and instantaneously close the open contacts (quick-make) with a momentary break in between. The quick-break feature provides for rapid full arc interruption, under maximum voltage and amperage, reducing contact erosion and increasing useful life.

Control components and wiring can be replaced without removing the RTS-30 transfer switch from its enclosure. The neatly arranged, front-connected, flame retardant, 600-volt SIS rated switchboard wiring simplifies electrical circuitry tracing. Heavy-duty control components and contacts ensure switching requirements are easily handled. All wiring connections are labeled with sleeve-type markers, easily visible from the front of the cabinet.

RTS-30 Series open-transition transfer switches are ideal for basic transfer applications and for high inductive load transfer applications. Featuring a quick-break, quick-make, high-speed transfer mechanism, they provide positive mechanical interlocking and simple electrical operators. The switches offer rapid arc quenching. The safe external manual operator provides the same quick-break, quick-make operation as an electrical operator. They are available in both 3- and 4-pole configurations and feature front accessible wiring.

Also available are RTS-30 Series closed-transition transfer switches, which offer rapid closed-transition retransfer to the preferred source and for testing - with zero power interruption. This switch provides high-speed quick-break, quick-make, open-transition transfer upon the loss of the preferred power source. These switches also feature simple electrical operators and rapid arc quenching. They are available in 2-, 3-, and 4-pole configurations and feature front accessible wiring.
