Quick Summary
Rittal 9677265 SV NH slimline switch disconnector isolates 3-pole power circuits up to 690 V. In compact panels, space constraints and installation complexity often slow projects; this unit minimizes footprint while preserving safety. It carries UL 94‑V0 fire-rated material and IEC/DIN EN 60 947‑3 compliance, reinforcing reliability in critical control panels. For NH size 2, with 185 mm bar spacing, cable outlet at the top, and screw attachment, it integrates quickly into distribution boards and motor control centers, reducing commissioning time and life-cycle costs. The robust 400 A rating supports demanding industrial loads while maintaining easy service access and predictable tripping behavior.

FAQs
Install with the screw attachment using the M12 mounting points, ensuring the device aligns with 185 mm center-to-center busbar spacing. Connect 6-240 mm² round conductors to the top cable outlet and tighten to recommended torque. Verify secure fastening and observe clearances for heat dissipation during commissioning.
The unit supports round conductors from 6 to 240 mm². Use the top cable outlet for direct routing and the M12 bolt connections for a secure mechanical hold. Confirm conductor insulation and crimping meet local standards before energizing.
Yes. It is rated for 690 V, 3-phase (3-pole) operation with a maximum current of 400 A, making it suitable for main isolation in 3‑phase distribution and motor control scenarios within its IEC/DIN EN 60 947-3 tested framework.
The device uses UL 94-V0 fire-rated polyamide housing and complies with IEC/DIN EN 60 947-3 testing. These certifications support safe operation in industrial control panels and align with common European safety requirements for electrical disconnectors.
This configuration matches standard European busbar layouts, enabling compact panel designs and straightforward integration into existing enclosures. It reduces required space, simplifies wiring routes, and supports faster assembly in panel-building and MCC applications.
