Overview

The Mersen 9F61CHM210 is a non-disconnecting fuse support designed for indoor installations, specifically within potential transformer circuits or applications where an independent isolating device is present. This component is part of Mersen's extensive line of medium voltage fuse supports and disconnect switches, ranging from 2.4kV to 38kV. The CHM series, identified by the SKU 9F61CHM210, is engineered for 25.8kV applications and accommodates fuses with a 3-inch ferrule diameter. It is suitable for vertical or horizontal mounting, offering installation flexibility. Fuse supports and disconnecting switches, including this model, feature live parts at both ends, ensuring secure connection points. It is crucial to note that while disconnecting switches offer isolation, they are not load-breaking devices; the circuit must be de-energized before fuse disconnection. The type EK designation signifies indoor use, differentiating it from the outdoor EKO series. This fuse support is compatible with Mersen's fuse offerings designed for specific voltage and current ratings. For detailed mounting, storage, and maintenance information, refer to Mersen's technical documentation (INST-EK39196). This product is proudly distributed by Gross Automation.
