Rittal NH Fuse-Switch Disconnectors
The Rittal NH Fuse-Switch Disconnectors are integral elements in low-voltage distribution and busbar systems, acting to ensure safe, reliable, and efficient power distribution. In contrast to conventional stand-alone switches, the Rittal NH Fuse-Switch Disconnectors can be easily connected with RiLine and the next generation RiLineX busbar systems, providing a more flexible and efficient solution for the current industrial power distribution.

Rittal NH disconnectors are primarily categorized by how they mount inside a cabinet. While traditional mounting-plate variants exist, Rittal’s core engineering focus is on drill-free busbar mounting
| Model | Mounting method | Electrical connection | Key selection difference |
|---|---|---|---|
| SV 9343000 | For 60 mm busbar systems | Box terminal | Busbar-mounted version with box terminals. |
| SV 9343010 | For 60 mm busbar systems | M8 screw connection | Busbar-mounted version with M8 screw connections. |
| SV 9344010 | Mounting plate installation | M8 screw connection | Mounting plate version with M8 screw connections; select according to the installation layout. |
SV 9343010 and SV 9344010 both use M8 screw connections, but their mounting methods differ. Choose SV 9343010 for a 60 mm busbar system and SV 9344010 for mounting plate installation. Do not select a replacement based on rated current alone; confirm the mounting method and terminal type before ordering.

FAQ
Q1. How do I choose the mounting method?
A: Choose busbar mounting for a compatible 60 mm busbar system, or mounting plate installation for separate fixing and wiring.
Q2. Box terminals or screw terminals?
A: Choose according to your conductors and cable connections. Confirm cable size, terminal compatibility and tightening torque.
Q3. Are NH fuse links included?
A: Confirm the quotation’s supply scope. The specified NH size indicates compatibility, not inclusion.
Q4. How do switch and fuse current ratings differ?
A: The switch rating defines its operating capacity. Select the fuse rating for the load and cable protection, within the switch’s limits.
Q5. Can an older RiLine60 switch be used on RiLineX?
A: Confirm Rittal approval for the exact model. Check mounting, busbar dimensions, contact protection and accessories.
Q6. What is needed for replacement or quotation?
A: Provide the model, quantity and delivery destination. For replacements, include installation photos, mounting details, voltage, fuse rating and cable connections.
