Overview

The Mersen 9F61AGG305 is a non-disconnecting fuse support designed for medium voltage applications, specifically for indoor installations. This unit is part of the Mersen EK-1 series, intended for use with fuses featuring a 3-inch ferrule diameter. It is primarily utilized in potential transformer circuits or in applications where an independent disconnecting or isolating device is already present in series with the fuse. The fuse support includes live parts for both ends, ensuring secure contact. It offers versatile mounting options, allowing for both vertical and horizontal installation to accommodate various panel layouts and space constraints. The 9F61AGG305 is engineered to meet the demands of electrical protection systems requiring reliable fuse holding capabilities. It is crucial to note that while this is a fuse support, it is not a load-breaking device. Therefore, the circuit must be open before any fuse disconnection or replacement is attempted. For applications requiring isolation, a separate disconnecting switch must be employed. This model is designed for indoor use, differentiating it from the EKO series which is for outdoor environments. The AGG series designation indicates compatibility with specific fuse sizes and configurations within the Mersen catalog. When selecting fuse supports and disconnect switches, it is imperative to ensure the clip centers and size precisely match the fuse being protected to guarantee optimal performance and safety. Refer to Mersen's technical documentation for detailed specifications and installation guidelines, including INST-EK39196 for comprehensive storage, mounting, and maintenance information.
