Rittal SV NH-zekering-lastscheidingsschakelaarmodule 9666.410, 250x450 mm, staalplaat, RAL 7035, 3-polig, 630 A

In industrial power distribution panels, technicians often need a safe and compact way to isolate and protect outgoing circuits. The Rittal SV NH fuse-switch disconnector module 9666.410 mounts directly onto 60 mm busbar systems, providing a robust 3-pole disconnection point for NH fuses from size 00 to 3. Its sheet steel enclosure in light grey (RAL 7035) blends seamlessly into standard switchgear, while the 250 mm width and 450 mm height ensure compatibility with common compartment layouts. Rated for 630 A at 690 V AC, this module is built to handle demanding low-voltage distribution tasks.
