Quick Summary
Rittal SV 9340.950 fuse base delivers reliable bus-mounting fuse protection for 3‑pole 400 V power distribution in control panels. Engineers face downtime from undetected fuse faults; this base features integral visual fuse monitoring via flashing indicator and operating status display. It is built to IEC/DIN EN 60 947-3 safety standards and uses UL 94‑V0 flame‑rated polyamide for robust enclosure material. This combination supports fast installation, easy maintenance, and cost-effective compliance in industrial cabinets while enabling clear fault diagnosis. With 60 mm centre spacing, box-terminal connections, and D‑Switch fuse inserts, you gain compatibility across assemblies and streamlined service workflows.

FAQs
Yes. SV 9340.950 is designed for D‑Switch fuse inserts (D01) with retaining springs and supports 1.5–25 mm² round conductors via a box-terminal connection. It also accommodates 60 mm busbar spacing, simplifying integration into existing layouts without major cabinet redesigns.
Key specs include a 63 A maximum operating current, 400 V rated operating voltage, and a 3‑pole configuration. The device uses a box-terminal connection for round conductors (1.5–25 mm²) and supports 100–400 V indicator lighting. Compliance references include IEC/DIN EN 60 947‑3 and UL 94‑V0 materials.
The product features UL 94‑V0 flame‑retardant polyamide, and its electrical safety references align with IEC/DIN EN 60 947‑3 standards. While CE marking is common for European products, ensure site procurement specifies CE where required; consult the datasheet for exact certification scope.
It's ideal for control cabinets, motor drive feeds, and centralized power distribution where reliable fuse protection with visible status indicators is valuable. The 60 mm busbar spacing and box-terminal connection support modular installations, traceable maintenance, and straightforward fault diagnosis in industrial automation lines.
Integrated fuse monitoring reduces silent faults and unnecessary downtime, while retaining springs and standardized fuse inserts streamline replacements. The durable UL 94‑V0 material and robust mounting lower long-term maintenance costs, and the 60 mm spacing aids future retrofits without extensive rewiring.
