Product description
SV NH slimline fuse-switch disconnector, size 2, 400 A, 690 V, 3-pole, bolt M12, 185 mm, single-pole, switchable, for current transformer installation
High-current, 3-pole design enables 400 A continuous operation, delivering dependable protection and switching in demanding power distribution. This translates to reduced fault impact and streamlined maintenance workflows in control panels and switchgear, especially where current transformer installation is required. UL 94-V0 rated polyamide housing and partially silver-plated hard copper contact tracks enhance safety and long-term durability, minimizing replacement frequency and service calls. The top/bottom cable outlet and bolt M12 connection support flexible, fast wiring while accommodating a conductor range of 6-240 mm², reducing installation time and wiring errors. The 185 mm bar spacing and NH size 2 compatibility ensure precise fit within standard busbar systems, lowering custom fabrication costs. When used on busbars with contact hazard protection covers, the noted contact terminal requirement prevents accidental contact, improving operator safety and compliance. Overall, the unit balances compact footprint with rugged performance for converter installations and space-constrained panels, delivering measurable efficiency gains and lower lifecycle cost.

FAQs
SV 9677.210 is designed for NH size 2 busbars with an 185 mm center-to-center spacing and accepts top or bottom cable exits. It uses a bolt M12 connection and supports conductor ranges from 6 to 240 mm², making it suitable for standard panel and switchgear configurations without custom adaptations.
The unit adheres to IEC/DIN EN 60 947-3 for performance testing and features a UL 94-V0 fire rating for the housing material, enhancing safety in automated environments. These certifications support compliance in many industrial markets and simplify procurement with established conformity expectations.
Yes. The SV 9677.210 is specified for current transformer installations, offering a 3-pole, switchable configuration that enables safe isolation and accurate integration with transformer circuits while maintaining space efficiency in control panels.
The fuse-switch disconnector has a width of 100 mm and a height of 670 mm. Each pack weighs 5.02 kg, with copper weight per piece at 1.73 kg, helping you assess enclosure footprint and cooling requirements during layout planning.
Use with busbars that require a contact hazard protection cover only after ensuring appropriate contact terminals are employed. This reduces the risk of electric contact, improves operator safety, and lowers downtime through easier maintenance, contributing to a favorable total cost of ownership in critical power-distribution applications.
