Why Choose the Rittal SV 9343.130 NH Fuse-Switch Disconnector?
The Rittal SV 9343.130 is a high-performance NH size 1 fuse-switch disconnector designed for direct use on 60 mm busbar systems. Rated for a maximum operating current of 250 A and an operating voltage range of 400–690 V AC, three-phase, it combines NH fuse protection, switching and isolation within a compact three-pole power distribution device.
Unlike box-terminal variants, the SV 9343.130 uses a robust M10 screw electrical connection and accepts round conductors from 10–150 mm². A 32 × 10 mm clamping area is provided for laminated copper bars, while the cable outlet may be positioned at the top or bottom to accommodate different switchgear layouts and conductor routing requirements.
The SV 9343.130 also incorporates electronic fuse monitoring, providing additional functionality for monitored industrial distribution systems. Its polyamide construction, silver-plated electrolytic copper contact tracks and compatibility with 5 mm and 10 mm thick busbars make it a purpose-designed solution for industrial switchgear, distribution panels and machine power systems.

Reliable NH Fuse Protection with M10 Connections
NH fuse-switch disconnectors combine high-current fuse protection with switching and isolation, providing an efficient method of protecting feeders and distribution circuits. The Rittal SV 9343.130 mounts directly onto a 60 mm busbar system and accepts NH size 1 fuse inserts, helping create a compact and organised industrial power distribution arrangement.
The M10 screw connection provides a robust termination method for conductors and busbar connections, while the 10–150 mm² round conductor range supports a broad selection of installation requirements. Combined with top or bottom cable routing and integrated electronic fuse monitoring, the SV 9343.130 provides a flexible solution for professionally engineered switchgear and distribution assemblies.
Typical Applications
- Rittal 60 mm busbar power distribution systems.
- Industrial switchgear assemblies.
- NH fuse-protected feeder circuits.
- Main and sub-distribution panels.
