    A drawout controller is a controller that may be removed from a cell without the unbolting of any connections or mounting supports. It utilizes specific interlock devices that function according to ANSI standards, which allow for the safe removal of the device with minimal risk to personnel. It is intended for use in SafeGear ®...

  • Page 18 When a 3-phase motor runs with one phase missing, the remaining 2 phases will take more load from the missing phase making them work harder, over heat and burn out. To avoid the above condition the SafeGear MCC controller has a blown fuse mech that envires thar all 3 phases and disconnect if only a single or two fuses blown. Blown fuse mechanism The fuse is working in the right position.
