D Switches are factory-wired, interconnected, and tested prior to shipment.
D All current-carrying components provide withstand current ratings in excess of those specified in UL-1008 standards.
D The contactor is electrically operated and mechanically held by a simple, over-center mechanism.
D The transfer switch has a double-throw, interlocked operation. Mechanical and electrical interlocks ensure proper sequence of operation.
D The transfer switch has segmented silver tungsten alloy contacts with separate arcing contacts on all sizes of switches. Transfer switches have arc quenching grids, enclosed arc chambers, and wide contact air gap to ensure superior source-to-source isolation on all units.
D The transfer switch components are accessible for inspection and maintenance without removal of the switch or the power conductors.
D A mechanical indicator and transparent chamber cover aid inspection, improve safety, and ease position designation.
D The disconnect switch inhibits transfer when activated.
D The automatic transfer switch is located on a drawout mechanism to facilitate maintenance.
D
Emergency power systems can be electrically tested without disturbing the load.
D Power cables do not have to be disconnected to remove the automatic transfer switch.
D The engine start circuit is maintained during bypass operation. Normal power failure causes the engine start contact to close even with the automatic transfer switch removed.
D The electrical controls are mounted on the enclosure door and connected by a wire harness and multipin disconnect plugs. The automatic transfer switch and/or the control panel may be tested, isolated, or removed for maintenance without load interruption.
D
Diagnostic lights and detailed instructions allow simple step-by-step operation.
D Bypass switch contacts are closed only during the bypass isolation operation.
D A silver-plated, copper bus interconnection for the automatic transfer switch and bypass switch is standard for all sizes of switches.
D The programmed transition function allows the load’s magnetic field to collapse before transferring to either source.
D Switching is accomplished by a dual DC solenoid drive for rapid operation and long life.
D
The time delay after the opening of the closed contacts and before the closing of the open contacts is adjustable.
D The transfer switch is suited for applications where the load consists of large motors and/or transformers.
The bypass-isolation transfer switch consists of two major components: an automatic transfer switch and a bypass-isolation switch.
The automatic transfer switch power switching components are available in standard and programmed-transition configurations and constructed for rugged, reliable operation.
The bypass section is a manually operated transfer switch that includes a manual load transfer handle and a control and interlock system. The switches are mounted in a compact enclosure and completely interconnected, requiring only the source and load connections. Once installed, no cables need to be removed to isolate the transfer switch module for maintenance or inspection.
Additional load-break contacts that cause load interruption during bypass-isolation functions are not required. The bypass- isolation switch contacts are out of the system’s current path except during actual bypass operation. Therefore, they are not constantly exposed to the destructive effects of potential fault currents. The normal source, emergency source, and load are connected between the automatic transfer switch and the bypass-isolation switch through solid-braced isolating contacts that open when the transfer switch is isolated.
The transfer switch has three positions:
D Automatic: The automatic transfer switch is supplying power to the load, and the bypass switch is in the open position. This position is the normal operating position.
D Test: The bypass switch is closed and supplying power to the load. The automatic transfer switch’s electrical controls are powered and the test switch on the enclosure door can be used to test the automatic transfer switch.
D Isolate: The bypass switch is closed and supplying power to the load. The automatic transfer switch is withdrawn from all power and is ready for maintenance.
The bypass-isolation switch has the same design as the transfer switch and thus has the same electrical ratings.
Manually operated, it features high-speed, quick-make, quick-break contact action. The bypass-isolation switch has three positions:
D Automatic: Normal bypass contacts open and emergency bypass contacts open
D Bypass Normal: Normal bypass contacts closed and emergency bypass contacts open
D Bypass Emergency: Normal bypass contacts open and emergency bypass contacts closed
