Overview

The Mersen 9F61CGL310 is an EKO-3D series outdoor fuse support designed for medium voltage applications up to 15.5kV. This non-disconnecting fuse support is primarily utilized in potential transformer circuits or in series with other disconnecting or isolating devices. It is crucial to note that while disconnecting switch devices offer isolation, they are not load-breaking and require the circuit to be open before fuse disconnection. The EKO series is specifically engineered for outdoor installations, providing robust protection in exposed environments. This model accommodates fuses with a 3-inch ferrule diameter and is suitable for vertical or horizontal mounting. The 9F61CGL310 includes live parts for both ends, ensuring secure contact. For applications requiring isolation, Mersen also offers disconnecting switch devices. When selecting a fuse support or disconnect switch, ensure the clip centers and size precisely match the fuse specifications. Mersen's commitment to quality and safety is evident in their comprehensive range of fuse supports and disconnect switches, designed to meet the stringent requirements of medium voltage power systems. This unit is manufactured in the USA.
