Product description
SV NH fuse-switch disconnector, size 2, 400 A, 690 V, 3-pole, box terminal
Feature → Business Impact → Application: The SV 9343.200 handles up to 400 A at 690 V in a 3-pole configuration, delivering secure, fast isolation that minimizes downtime and enhances operator safety in switchgear and control cabinets. Application: Ideal for panel builders and industrial automation environments requiring robust protection during maintenance and fault events. The box-terminal connection and top/bottom cable outlets simplify field wiring, reducing installation time and wiring errors. Benefit: Shorter commissioning times and improved reliability in high-current panels.Feature → Business Impact → Application: Clamping areas for laminated copper bars (32 mm width, 10 mm height) plus round conductor support (95–300 mm²) enable flexible conductor sizing. Application: Supports both copper bar busbars and round conductors in power distribution schemes. Benefit: Optimized current paths with lower contact resistance, improving efficiency and thermal performance.Feature → Business Impact → Application: Box-terminal design and centre-to-centre busbar spacing of 60 mm simplify integration with existing NH-sized distribution systems. Application: Compatible with standard modular enclosures and centre-to-centre layouts. Benefit: Easy retrofit and scalable panel design, reducing redesign costs.Feature → Business Impact → Application: 210 mm x 298 mm footprint and 3.64 kg per pack give a compact, manageable install with predictable weight loads. Application: Good fit for compact control panels and space-constrained switchgear. Benefit: Streamlined mounting, easier service access, and predictable logistics in assemblies.Feature → Business Impact → Application: Certified for safety with 690 V, 3‑phase operation and documented test standard IEC/DIN EN 60 947-3. Application: Critical in power distribution and safety-compliance workflows. Benefit: Regulatory alignment and risk mitigation for critical infrastructure projects.

FAQs

The SV 9343.200 uses a box-terminal connection designed for NH size 2 busbar schemes and supports two wiring modalities: top or bottom cable outlets for both laminated copper bars and round conductors (95–300 mm²). Installation benefits include straightforward alignment with a 60 mm busbar centre spacing and compatibility with standard enclosure footprints, reducing wiring errors and commissioning time.
Key specs are 400 A rated operating current, 690 V rated operating voltage, and 3-pole configuration. These allow reliable isolation and switching of high-current circuits in industrial controls, with copper contacts providing low resistance and robust current carrying capability, improving overall system efficiency and thermal management.
This unit is well-suited for power management and distribution in manufacturing, process automation, and switchgear panels. It supports control cabinets requiring reliable isolation, quick maintenance, and compatibility with laminated copper bar or round conductor wiring, making it a fit for OEM panel builders and system integrators.
The component uses UL 94 flame-rated polyamide material, is tested to IEC/DIN EN 60 947-3 safety standards, and operates at 690 V for three-phase systems. These certifications support compliance during design reviews and installation in regulated industrial environments.
Maintenance is streamlined by the box-terminal design and defined connection options, reducing fault-finding time. The copper weight (1 kg per piece) and robust contacts improve longevity and lower contact resistance, contributing to reduced operating losses and a faster payback in high-demand panels.
