Quick Summary
SV NH fuse-switch disconnector from Rittal provides reliable isolation for 3-pole switchgear in industrial control panels. Operators often struggle with safe isolation during commissioning and routine maintenance, risking arc flash and extended downtime. This unit complies with IEC/DIN EN 60 947-3 and UL 94-rated housing, delivering both electrical safety and fire resistance in harsh environments. For panel builders, its robust box-terminal connection and compatibility with laminated copper bars streamline installation and reduce wiring errors. By combining precise mechanical fit, clear labelling, and proven durability, it supports faster commissioning, easier servicing, and a lower total cost of ownership through longer service intervals and reduced maintenance cycles.

Product description
SV NH fuse-switch disconnector, size 00, 160 A, 690 V, 3-pole, box terminal
Compact NH size 00 construction minimizes enclosure footprint while maintaining robust current carrying capacity. Business impact: saves panel space and reduces panel size costs while delivering reliable isolation up to 160 A at 690 V. Application: suited for modular switchgear in compact automation cabinets with 60 mm busbar spacing. Box-terminal connection provides a durable, slip-free conductor interface, reducing torque requirements and ensuring consistent contact force. Business impact: lowers field servicing time and improves electrical reliability, cutting downtime during maintenance. Application: ideal for laminated copper bar systems with 13x13 mm clamping area. Top/bottom cable outlets offer flexible routing, enabling neat wiring and easier retrofits in existing enclosures. Business impact: easier installation and future re-wiring; compatible with 4–95 mm² round conductors. Application: use with 60 mm center-to-center busbar spacing and 5/10 mm height busbars. Material and safety: polyamide housing with UL 94 fire protection; silver-plated copper contact tracks ensure low contact resistance. Business impact: enhanced safety and long-term performance, reducing replacement risk. Application: suitable for demanding industrial environments where heat and flame resistance matter. Compliance and fit: IEC/DIN EN 60 947-3 test specification, 3-pole configuration, 160 A rating, and a box terminal connection for reliable, plug-and-play integration. Business impact: ensures regulatory alignment and faster acceptance in audits. Application: integrates with standard busbar systems and UR note considerations.

FAQs
The device is designed for NH size 00 assemblies, with a 3-pole configuration and 60 mm center-to-center busbar spacing. It uses a box-terminal connection and accepts 4–95 mm² round conductors. The clamping area (13 x 13 mm) supports laminated copper bars, enabling a robust, vibration-resistant interface. This makes it straightforward to integrate into compact control panels and existing switchgear skins without reworking the busbar system.
This fuse-switch disconnector is rated for a maximum operating current of 160 A and a rated operating voltage of 690 V (3-phase). It is specified as a 3-pole unit for NH size 00, with top/bottom cable outlets and a box-terminal connection, ensuring reliable disconnection and safe isolation during commissioning and routine maintenance.
UR applications are explicitly mentioned in the data note: typical UR adaptations require Special Purpose Fuses. For standard UR use, verify compatibility with Pir and UR modifications from Rittal. In general, the base 9343000 configuration is designed for conventional panel builds with laminated copper bars, but UR-specific configurations should be validated before deployment.
The product aligns with IEC/DIN EN 60 947-3 for electrical safety testing, and the housing material provides UL 94 flame protection. Its box-terminal design and copper contact tracks support durable, compliant operation in industrial environments, offering predictable performance during audits and routine safety checks.
Regular inspection of the copper contact surfaces, verification of the box-terminal connections, and checking cable outlet routing help maintain low contact resistance and reliable isolation. The 3-pole, 160 A rating supports predictable overload behavior, while the robust polyamide housing and silver-plated contacts reduce wear. Document service intervals to optimize uptime and lifecycle cost.
