Instructional Booklet Effective: March 2007 Fixed and Drawout Magnum Transfer Switches The components comprising the three panels are installed in accordance with the specific requirements of the circuit being controlled. Each transfer switch is, therefore, tailor-made to a specific application. 3.2 Power Panel The power panel consists of a means for making load, power, and neutral connections. The main contacts and the transfer mechanism are all on one steel frame (Figure 12).
Instructional Booklet Page 12 Effective: March 2007 Fixed and Drawout Magnum Transfer Switches 3.2.4 TRANSFER MECHANISM The transfer switch uses Eaton Magnum insulated case switching devices and insulated case switches with a stored-energy mechanism. An electrical operator automatically recharges the mechanism after the switching device has been closed, and an indicator on the switch shows whether it is in the OPEN or CLOSED position and the status of the stored energy mechanism.
