UL TESTED, LISTED, AND LABELED
Russelectric was the industry leader in obtaining UL listing for its medium-voltage transfer switchgear. All Russelectric RTS Series circuit breaker automatic transfer switches have been fully UL tested, listed, and labeled under UL 1008A. In addition, all Russelectric medium-voltage transfer switchgear (operating above 600 volts and below 15 kV) is listed per UL category “Circuit Breakers and Metal-Clad Switchgear – Over 600 Volts (DLAH)”. It is also designed, manufactured, and tested to meet or exceed stringent IEEE, NEMA, and ANSI standards.
RUGGED HIGH SPEED SWITCHING DEVICES
Russelectric RTS Series Russelectric Medium-Voltage Circuit Breaker type Automatic Transfer Switches are designed to transfer electrical loads from a normal power source to an emergency power source upon reduction or loss of voltage and to retransfer loads when normal power is restored.
Supervised by the advanced RPTCS microprocessor control, Russelectric Medium-Voltage Circuit Breaker Automatic Transfer Switches direct the flow of electric power through the carefully timed openingclosing of circuit breakers.

DESIGNED, FOR MAXIMUM SAFETY AND OPERATING SIMPLICITY
Switches are designed to provide maximum protection for operators and maintenance personnel and to minimize the danger of operator error. Drawout modules, metal-clad construction, segregation of controls from power elements, and separately accessible grounded compartments are all part of Russelectric’s design safety philosophy.
All switches are designed for unattended automatic operation, but include controls for manual operation. Designs provide accessibility for maintenance, trouble-shooting, and component replacement.
All switches are factory tested for functionality prior to shipment. Interconnect wiring diagrams enable proper interfacing of switches.
DESIGN, MANUFACTURE, AND TESTING
All bus is formed, cut, and punched before being insulated with high-dielectric epoxy coating to guarantee the integrity of the insulation and ensure maximum performance. Busbars pass through
track-resistant, polyester glass barriers between cubicles. Main bus joints have silver-plated connections and are insulated with preformed boots.
All transfer switches are thoroughly inspected and tested both mechanically and electrically under simulated operating conditions before shipment.
