Fixed and Drawout Magnum Transfer Switches

In addition, a fixed switching device does not have a standard fea- ture to hold the switching device in a “trip-free” position.

Magnum fixed switching device terminals have holes for making bolted horizontal primary bus connections. Adapters are available for making vertical primary bus connections. Secondary connec- tions can be made through standard terminal blocks or a special connector compatible with the drawout switching device’s type secondary connector. Both secondary connection devices are mounted at the top front of the switching device.

The Magnum fixed switching devices have two mounting feet, one on each side, to permit the switching device to be securely mounted to the transfer switch frame. Each mounting foot has two slotted mounting holes to facilitate mounting.

1.4 Transfer Switch Catalog Number Identification

Transfer switch equipment catalog numbers provide a significant amount of relevant information that pertains to a particular piece of equipment. The catalog number identification table (Table 3) provides the required interpretation information. An example for an open transition switch is offered to initially simplify the pro- cess.

Example: Catalog Number (circled numbers correspond to position headings in Table 3).

The catalog number ATVIMGB33200XRU describes an ATS with the switching devices mounted vertically in the enclosure. The intelligence, represented by the ATC-400/ATC-600/ATC-800, is a microprocessor-based logic package. The Magnum Breaker is used as the switching device and is a 3-pole molded case breaker for each source. The continuous current rating of this equipment is 3200 A and is applicable at 480/277 Vac, 60 Hz. The transfer switch equipment is enclosed in a NEMA 3R enclosure and is listed for Underwriters Laboratories (UL) and Canadian Standards Association (CSA) applications.
