The RTSCD line of transfer switches deliver Russelectric’s legendary
reputation for quality and reliability in a commercial duty switch.
The RTSCD has a user friendly operator interface panel (O.I.P.), which
utilizes softkeys and intuitive operation. Like all Russelectric transfer
switches, the RTSCD features preloaded springs and an electric operator-driven
over-center mechanism for extremely quick switching operations. This unique
ATS design instantaneously opens and closes the ATS contacts and provides for
rapid full arc interruption, even under maximum voltage and amperage. This
considerably reduces contact erosion and effectively increases the switch’s
useful life.
A manual operator is permanently fixed to the ATS switching chassis.
Example: RTSCD – ASA2603 AMW 1XXXX- Service Entrance Transfer Switch Open Transition, 260A,3 Polewith Solid Neutral, 480/277V, No Accessories.
