Mersen 9F61AGG301 - Fuse 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. Disconnecting 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. Fuse supports and disconnecting switches include live parts for both ends. Both 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. 15500 Volts EK-1D AGG series.

Overview

The Mersen 9F61AGG301 is a non-disconnecting fuse support from the AGG series, specifically designed for indoor installations. This unit is rated for 15,500 Volts and is intended for use in potential transformer circuits or applications where an independent disconnecting or isolating device is present in series with the fuse. It's crucial to note that while this device provides support, it is not a load-breaking component; the circuit must be de-energized before fuse disconnection. The AGG series supports live parts at both ends and offers versatile mounting options, allowing for vertical or horizontal installation to suit various panel configurations. This particular model, the EK-1D, is engineered for the 'D' fuse size, which corresponds to a 3-inch ferrule diameter. Mersen's fuse supports and disconnect switches are built to stringent standards, ensuring reliable performance in medium voltage applications. When selecting a mounting for a current-limiting fuse, it is essential that the clip centers and size precisely match the fuse selected. For detailed information on storage, mounting, and maintenance, consult Mersen's INST-EK39196 documentation. This fuse support is proudly distributed by Gross Automation, your trusted partner for industrial electrical components.
