Type EK 961 Series Medium Voltage use Holders & lips USE LOKS & HOLERS USE SUPPORTS, USE ISONNET SWITHES, AN AESSORIES ROM 2.4KV TO 38KV use supports, non-disconnecting, are used primarily in potential transformer circuits, or where there is some other disconnecting or isolating device in series with the fuse in the circuit. isconnecting switch devices have the additional feature of serving to isolate the equipment they protect. It should be noted that disconnecting switches are not load-breaking devices, therefore, the circuit must be open prior to the fuse disconnection. Select either a fuse support or a disconnecting switch for each fuse. use supports and disconnecting switches include live parts for both ends. oth fuse supports and fuse disconnect switches can be mounted vertically or horizontally. The type EK are used for indoor installations while the type EKO are used outdoors. Indoor: use supports:...ek-1 use disconnect switches:... EK-3 The letter suffix following the (-1) or the (-3) shows the fuse size. When selecting a mounting for a current-limiting fuse, it is necessary that the clip centers and size agree with the fuse selected. Outdoor: use supports:...eko-1 use disconnect switches:....

These spring reinforced clips will accomodate one and two barrel 3-inch diameter medium voltage ferrule type fuses. The clip and reinforcing spring are intended to be bolted to a copper busbar through two.41 and 1.06 slots. A minimum copper-bus section of 1/4 x 1-1/2 is recommended for maximum ratings of 24R and 450E. The at # 228-700-530 is for one pair of clips, enough for one fuse. 52 EP.MERSEN.OM
