Non-Automatic Transfer Switches- RTS Series

,

Russelectric RTS Series non-automatic transfer switches are ideal for applications in which immediate restoration of service (after loss of the normal source) is not critical, and local operations personnel are available to initiate transfer. These switches are UL-listed double-throw devices with identical withstand ratings and design characteristics to RTS Series automatic transfer switches.

Since these non-automatic switches are identical in design to Russelectric RTS Series automatic transfer switches and are of the same exceptional quality, users can be con dent that they are time- tested, reliable, and safe.

Operations personnel can initiate a source transfer locally using electrically operated push-buttons or a mechanical external manual operator, or remotely (optional).

All non-automatic 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 30-cycle and 3-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.

Automatic Transfer Switches- RTS-30 Series

,

Russelectric RTS-30 Series automatic transfer switches are the most complete line of 480 VAC 30-cycle and 3-cycle UL tested switches available today.

Tested, Listed, and Labeled by UL 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-30 Series transfer switches have UL listed closing and withstand ratings of 200,000 amperes.

High-Performance Design

Russelectric automatic transfer switches are modern, high-speed switching devices designed to transfer electrical loads from a preferred power source to an alternate power source when voltage and/or frequency varies from preset limits, and to retransfer loads when preferred source is restored.

Russelectric RTS-30 Series automatic transfer switches utilize simple electrical operators to provide high-speed quick- break, quick-make, preloaded transfers. The operators are connected to the switch mechanism by precision self- aligning, ball joints and sturdy linkage rods which prevent misalignment.

Built Rugged for Long Life, Minimum Maintenance, and Trouble-Free Service

Russelectric builds all its transfer switches for years of reliable, trouble- free operation with a minimum of maintenance. In fact, many Russelectric switches have been in continuous service for over 40 years.

Contact assemblies are designed to handle the rigors of 30-cycle closing and withstand performance and offer exceptional arc – and track-resistance. Segmented contacts are, machined (not cast, forged, or stamped) from solid copper. Main contact pad material is designed to prevent overheating, and stationary contact pad material prevents welding during withstand conditions. Brush movement of main contacts cleans contact pads with every operation.

30-Cycle-Rated transfer switches

Russelectric® RTS-30 Series Transfer Switches are UL labeled and listed for 30-cycle closing and withstand ratings based on testing per UL Standard 1008.  These switches dramatically simplify selective coordination of overcurrent/short circuit devices in emergency and backup power systems for healthcare and other mission critical facilities.

Capable of closing in on and withstanding 30 cycles of fault current, Russelectric RTS-30 Series Transfer Switches have the withstand capacity to allow downstream devices to clear a fault before upstream devices.  Consequently, they greatly simplify the engineering task of selective coordination mandated by the National Electrical Code for emergency and legally required standby systems.  RTS-30 & RTS-3 Series switches are available in single -and dual-operator versions in ratings from 100 to 4000 amps for either open -or closed-transition switching. 30 and 3-cycle-rated (RTS-30 & RTS-03) Series Bypass/Isolation Switches are also available in load-break bypass and no load-break bypass versions.  No other manufacturer offers such a comprehensive range of 30 and 3-cycle-rated switches.

Russelectric RTS Series switches come equipped with the new RPTCS — the industry’s most powerful, most versatile microprocessor-based transfer control system.
