Product description
SV NH slimline fuse-switch disconnector, size 00, 160 A, 690 V, 3-pole, screw M8, 185 mm, for current transformer installation
3-pole, 690 V capability with 160 A rating ensures safe disconnection of heavy loads in industrial panels. This translates to reliable protection for motors and feeders, reducing risk of arc flash during maintenance and enabling consistent uptime in automation lines. The polyamide housing with UL 94-V0 fire protection provides improved fire safety in cabinets and control rooms, supporting compliance in harsh environments. Top/bottom cable outlets offer installation flexibility, simplifying wiring layouts and reducing time to connect CTs, feeders, and auxiliary circuits. Screw M8 terminals deliver robust, vibration-resistant connections, improving long-term reliability and reducing maintenance needs in active systems. The device’s dimensions (Width 50 mm; Height 670 mm) and weight (2.65 kg per pack; copper weight 0.6 kg) support compact panel designs while preserving accessible serviceability. Compatibility with 185 mm bar spacing ensures seamless integration with common busbar layouts, minimizing layout changes during retrofits. Note the specification requires contact-terminal use when busbars have protective covers, ensuring safe operation across sealed installations.
