Mersen 9F61AEG205 - 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-3C AEG series.

Overview

The Mersen 9F61AEG205 is a 15.5kV indoor fuse support designed for potential transformer circuits or applications requiring a non-disconnecting fuse holder. This fuse support is part of Mersen's EK-1 series, engineered for medium voltage systems ranging from 2.4kV to 38kV. The 9F61AEG205 accommodates 3-inch ferrule diameter fuses (C size) and is rated for 15.5kV with a 50kA interrupting rating, making it suitable for critical protection in utility and industrial installations. Key features include live parts for both ends, allowing for vertical or horizontal mounting configurations. Unlike disconnecting switches, this non-disconnecting fuse support requires an external isolating device in series with the fuse for safe operation. The EK-1 series is specifically designed for indoor applications, ensuring reliable performance in controlled environments. Applications include potential transformer circuits, metering installations, and secondary protection in medium voltage systems. The 9F61AEG205 is manufactured by Mersen in the US and distributed by Gross Automation. For detailed mounting and maintenance instructions, refer to Mersen's INST-EK39196 documentation. Compatibility is ensured with Mersen's 9F60/9F62 series fuses, including the Amp-Trap® CS-3 series and HelioProtection® photovoltaic fuses. The fuse clips and live parts are available as spare components for easy maintenance and replacement.
