Product description
SV NH fuse-switch disconnector, size 2, 400 A, 690 V, 3-pole, screw M10
High current rating up to 400 A enables reliable switching for demanding loads, reducing panel size and maintenance intervals while supporting motor control and distribution reliability. This translates to lower lifecycle costs and improved uptime in manufacturing lines. The 690 V operating voltage ensures compatibility with European standard power networks, enhancing regulatory compliance and machine safety. The 3-pole design provides balanced isolation across phases, improving fault detection and preventing arc events in critical power circuits. Top/bottom cable outlets simplify wiring access during panel build, speeding assembly and reducing installation errors in tight enclosures. Copper weight and copper contact surfaces offer low contact resistance, translating to consistent performance over time and reduced heat buildup during switching. UL 94 fire-protection and IEC/DIN EN 60 947-3 conformance give integrators confidence in safety and certification requirements for equipment in process industries. Compatibility with laminated copper bars up to 50x10 mm and busbar spacing of 60 mm supports standardized panel architectures, making replacement parts straightforward for service teams and OEMs. For installers, the screw M10 connection and clear mounting footprint minimize tool downtime and misalignment, while the compact 210x298 mm footprint enables flexible placement within switchgear cabinets.
