Overview

The Mersen 9F61AGJ205 is a non-disconnecting fuse support designed for critical applications, primarily in potential transformer circuits or where an independent isolating device is present. This indoor-rated support, part of the AGJ series, is engineered for 15.5kV systems and is suitable for vertical or horizontal mounting. It features live parts for both ends, ensuring secure fuse contact. The 9F61AGJ205 is specifically designed to accommodate fuses with a 3-inch ferrule diameter, as indicated by the 'AGJ' designation and the 'D' fuse size suffix in Mersen's cataloging system. This product is ideal for ensuring reliable fuse protection in medium voltage installations where circuit isolation is handled by a separate device. Mersen's commitment to quality and safety is evident in the robust construction of these fuse supports. For applications requiring isolation, a Mersen fuse disconnect switch should be selected instead. Ensure the circuit is open before fuse disconnection, as disconnecting switches are not load-breaking devices. This unit is proudly manufactured in the US. For detailed installation, storage, and maintenance information, refer to Mersen's INST-EK39196 documentation.
