Product description
SV NH fuse-switch disconnector, size 00, 160 A, 690 V, 3-pole, box terminal, with electromechanical fuse monitoring
The NH size 00, 3-pole design provides a compact yet robust disconnection solution rated for 160 A at 690 V. This reduces panel footprint while maintaining safe isolation, ideal for central power distribution in control cabinets. Box terminal connections with top/bottom cable outlets simplify wiring and serviceability, enabling faster, cleaner installation and reducing error rates in challenging production environments. Clamping area for laminated copper bars (13x13 mm) and 60 mm busbar centers ensure reliable current sharing and low resistance paths, supporting dependable operation in high-demand lines. The polyamide body with UL 94 fire protection adds safety and regulatory confidence, while IEC/DIN EN 60 947-3 testing confirms suitability for fuse-switch devices. Electromechanical fuse monitoring provides proactive fault detection, minimizing unplanned downtime and extending cabinet life. Weight, dimensions, and mounting footprint (106 mm width, 194 mm height, 1.06 kg per pack) allow predictable enclosure planning and straightforward replacement in standard control cabinets. Overall, the unit delivers robust protection, wiring flexibility (top/bottom outlets, 4–95 mm² conductors), and easy integration with factory busbar systems.
