Product description
SV NH fuse-switch disconnector, size 3, 630 A, 690 V, 3-pole, screw M10
Feature → Business Impact → Application: The 3-pole design rated up to 630 A at 690 V enables high-current switching with a single device, reducing component count and potential fault points in switchgear. This translates to faster assembly, lower installation costs, and improved system availability in manufacturing lines and process automation. Feature → Business Impact → Application: Screw M10 connections and a 50 mm x 10 mm clamping area for laminated copper bars provide secure, low-impedance terminations. This supports reliable conductor transitions in control cabinets and battery of feeders, minimizing voltage drop and maintenance needs across panel installations. Feature → Business Impact → Application: Top/bottom cable outlets and a 60 mm center-to-center busbar spacing facilitate flexible routing and predictable layout in compact enclosures, reducing cabinet depth requirements and simplifying upgrades in evolving automation cells. Feature → Business Impact → Application: Dimensions of 250 mm width and 298 mm height, plus a weight of 4.22 kg per pack, offer a balanced footprint for modular enclosure designs, easing shipping, storage, and on-site handling. Feature → Business Impact → Application: The copper weight of 1.44 kg per piece provides robust conductor mass for low resistance, supporting stable performance in high-current applications; UR usage requires Special Purpose Fuses, which clarifies installation boundaries and prevents misapplication.

FAQs
The unit provides a 50 mm wide by 10 mm high clamping area for laminated copper bars and supports busbar center-to-center spacing of 60 mm, with top or bottom cable outlets and M10 screw connections, enabling secure, straightforward mounting in standard switchgear panels.
It is rated for 630 A at 690 V AC, 3-pole, NH size 3, with screw M10 terminals, making it suitable for high-current distribution in industrial control cabinets and machine panels.
UR applications are allowed only in conjunction with Special Purpose Fuses, per the provided note, which helps ensure correct protection coordination and prevents improper usage in UR configurations.
The device references IEC/DIN EN 60 947-3 for testing and UL 94 flame-rated material, with CE/on-market suitability typical for industrial cabinets, supporting compliance in regulated automation environments.
High current rating reduces the number of components, while secure copper terminations and configurable cable routing shorten assembly times and minimize downtime. The documented mass and copper weight support predictable maintenance planning and spare-part management in continuous-operation facilities.
