Quick Summary
Rittal SV 9343.350 fuse-switch is a high-capacity disconnect designed for safe isolation in control panels and industrial machinery. Operators often struggle with unreliable isolation, space constraints, and maintenance delays in high-current switchgear. It complies with IEC/DIN EN 60 947-3, uses UL 94 fire-rated polyamide, and is CE marked for global deployments. With 3 poles, NH size 3, 690 V operation, and electromechanical fuse monitoring, installation becomes straightforward and safer. The design supports top or bottom cable outlets, 60 mm busbar spacing, and copper/terminal specs that streamline panel builds and reduce stocking complexity. This translates to lower downtime, improved reliability, and smoother regulatory compliance across demanding automation environments.

FAQs
The SV 9343.350 is rated for up to 630 A and 690 V (three-pole configuration). It is designed to handle demanding industrial loads while maintaining safe, reliable isolation. The device supports NH size 3 and is compatible with 10–300 mm² round conductors, enabling robust power distribution in panel assemblies.
NH size 3 directly informs the mounting footprint and connection method. With screw M10 terminals and a 60 mm center-to-center busbar spacing, the unit integrates smoothly into standard busbar systems, reduces assembly time, and improves wiring discipline in compact control cabinets. Top or bottom cable outlets further simplify routing in crowded panels.
Yes. The SV 9343.350 is tested to IEC/DIN EN 60 947-3 standards, uses UL 94 fire-rated polyamide materials, and carries CE marking for European installations. This combination supports regulatory compliance, safer material choices, and reliable performance in diverse industrial environments.
Electromechanical fuse monitoring provides real-time fault indication, verification of fuse integrity, and proactive maintenance capabilities. This reduces unexpected outages, streamlines fault diagnosis, and improves maintenance planning, translating to higher equipment uptime and reduced operating costs in continuous production lines.
Plan for top or bottom cable outlets, M10 screw terminations, and 10–300 mm² conductor compatibility. The unit weighs about 4.58 kg per pack, with a copper weight of 1.44 kg per piece, and has dimensions of 250 × 298 mm. Consider 60 mm busbar spacing and 5–10 mm busbar to fit height adjustments when integrating into existing switchgear.
