Rittal 9343110 SV NH fuse-switch disconnector - 3-pole, M10

Feature: The SV NH fuse-switch disconnector is a 3-pole device rated for 250 A at 690 V with screw M10 terminals. Business impact: This combination delivers safe, maintenance-friendly isolation for high-power panels, reducing the risk of mis-wiring and unplanned downtime. Application: Ideal for panel builders integrating NH size 1 components in industrial switchgear and power distribution enclosures. The compact footprint and robust construction support reliable service in demanding environments, including enclosed control rooms and outdoor cabinets. Feature: UL 94 fire-rated polyamide housing paired with electroplated copper contact tracks provides durable, low-resistance connections. Business impact: Enhances safety margins under normal and fault conditions while maintaining high-current performance. Application: Suitable for harsh environments and compact enclosures where heat and arc fault risk must be minimized. Additional benefits: copper contacts are silver-plated for corrosion resistance and long-term reliability, reducing maintenance cycles and replacement costs. Feature: Clamping area for laminated copper bars with 32 mm width and 10 mm height supports 60 mm center-to-center busbar spacing, plus compatibility with standard bar systems. Business impact: Streamlines mechanical mounting, reduces part count, and accelerates installation. Application: Ideal for converting power distribution layouts to robust busbar networks. The 60 mm spacing aligns with common European panel designs, and the clamp dimensions ensure a secure grip on varied copper bar thicknesses. Feature: Top and bottom cable outlets plus a wide range of conductor sizes 10–150 mm² support flexible wiring in compact panels. Business impact: Simplifies routing, reduces rework, and enables faster commissioning. Application: Particularly beneficial in control cabinets with limited rear space and mixed conductor configurations. The design also supports easy inspection and testing of connections in maintenance cycles. Feature: Weight per pack 2.26 kg; copper weight 0.44 kg per piece; EAN 4028177540330; Customs tariff 85369095. Business impact: Improves BOM accuracy, logistics planning, and spare-part readiness for field service. Application: Facilitates procurement, inventory management, and standardized replacements across multiple installations. Feature: Safety and compliance notes include IEC/DIN EN 60 947-3 test specification and UL 94 fire-rating; UR variations may apply for specific applications. Business impact: Helps ensure regulatory compliance and reduces risk of non-conformance in audited facilities. Application: Relevant to industrial facilities, data centers, and process automation environments requiring robust isolation devices.
