Product description
SV NH slimline switch disconnector, size 3, 630 A, 400 V, 3-pole, bolt M12, 185 mm, cable outet bottom, screw attachment
The SV 9677.380 provides a 3-pole, 630 A, 400 V rating, enabling high-current distribution with a single device and reducing wiring complexity in panel builds for faster commissioning in industrial automation. Its 185 mm center-to-center busbar spacing and NH size 3 compatibility ensure a compact, scalable solution for standard switchgear, supporting reliable power delivery in manufacturing lines and data centers. The automatic quick-break contact delivers operator-independent switching, enhancing safety margins during start-up and routine maintenance, and reducing arc risks in critical lines. Flame-retardant polyamide housing with UL 94-V0 certification increases electrical cabinet safety while the partially silver-plated hard copper contact tracks minimize resistance under high current. Bottom cable outlet and screw M12 connection simplify wiring layouts, enabling 6-240 mm² conductors for flexible feeder configurations. The unit’s dimensions, 100 mm width and 941 mm height, along with a 15.7 kg pack weight and 4.78 kg copper per piece, deliver a robust, serviceable solution suitable for dense, modular installations in control cabinets. IEC/DIN EN 60 947-3 testing and ETIM/ECLASS references support compliance and easy procurement, while screw attachment mounting and busbar compatibility ensure straightforward installation.

FAQs
Installers should plan for the 185 mm center-to-center busbar spacing and the 100 mm width with 941 mm height to fit within standard EN/IEC switchgear footprints. The device uses screw attachment with M12 connections and supports 6-240 mm² conductors, making it compatible with common cabinet layouts and minimizing wiring complexity during integration.
The unit is tested to IEC/DIN EN 60 947-3 and features UL 94-V0 flame retardant material, reflecting compliance with essential safety and performance requirements for electrical disconnects. These certifications simplify supplier qualification, ensure regulatory alignment in many regions, and support risk management during audits and inspections.
Yes. The connection supports 6-240 mm² round conductors, and the bottom cable outlet provides flexible wiring options. The screw M12 interface combined with screw attachment mounting facilitates a secure, service-friendly installation within standard enclosures while preserving a clean internal layout in high-current panels.
It consolidates high-current isolation into a compact, robust device, reducing part count and wiring complexity. The product enhances safety through automatic quick-break action, improves uptime by lowering maintenance risk, and supports scalable power management across NH busbar systems, contributing to faster commissioning and lower total cost of ownership.
Ensure the enclosure supports NH size 3 with 185 mm busbar spacing and that mounting is via the screw attachment method with M12 terminals. Plan for the 100 mm by 941 mm footprint and weight considerations (15.7 kg per pack, copper 4.78 kg) during handling and service. Regular inspection of copper contacts will maintain low resistance and reliable switching over time.
