Rittal 9344130 SV NH fuse-switch disconnector EN 60 947-3

Feature to benefit mapping is used to convey how the SV NH fuse-switch disconnector supports business outcomes. The device offers a 3-pole design rated to 250 A for reliable heavy-current isolation in 400–690 V systems, enabling safer, more efficient panel layouts and reducing downtime during maintenance. The mounting plate assembly compatibility streamlines integration with existing switchgear, which translates to faster project timelines and lower installation costs. A top/bottom cable outlet configuration provides flexible routing in tight spaces, improving cable management and reduces wiring errors. The UL 94 compliant polyamide housing enhances fire safety in control cabinets, increasing overall system reliability in critical environments. Copper contact tracks plated with silver ensure low resistance connections, improving electrical performance and extending component life in laminated copper bar applications. With a 32×10 mm clamping area for laminated copper bars and a copper weight of 0.3 kg per piece, installers gain robust, repeatable terminations in compact footprints. The device supports 10–150 mm² conductor connections and 400–690 V operation, offering versatility for mixed installations and future scalability. Electronic fuse monitoring adds visibility into fuse status, enabling proactive maintenance and faster fault resolution, which lowers total cost of ownership in industrial automation and power distribution workstreams.
