1.3.2 Magnum Drawout Switching Devices

The Magnum drawout switching device is a design having three positions with the compartment door closed (CONNECT, TEST, DISCONNECT) and one position out of its compartment on the extendable carriage rails (REMOVE). The Magnum drawout switching device is equipped with both primary and secondary dis- connects to provide for the drawout functioning. The operating mechanism is a two-step, stored energy mechanism, either manu- ally or electrically operated. When withdrawn on the extendable carriage rails, Magnum switching devices can be inspected, acces- sory items added, and minor maintenance performed. The inside of the compartment can also be inspected with the switching device withdrawn on the extendable carriage rails.
