Product description
SV current transformer 250 A/5 A for NH slimline fuse-switch disconnector size 1-3 (SV 9677.XXX)
Compact top-mount integration with 185 mm centre-to-centre spacing enables space-saving installation and keeps enclosure depth unchanged, simplifying retrofits and layout planning in control panels. This directly reduces cabinet footprint and wiring complexity, speeding commissioning in NH slimline systems. The rated power input of 2.5 VA lowers the burden on measurement circuits, reducing heat generation and enabling cleaner signal conditioning for accurate monitoring. With a primary of 250 A and a secondary of 5 A alongside accuracy class 1, users gain dependable current readings critical for protection coordination and load management in feeders and switchgear. Box terminals, conductor range 2.5–4 mm², and polyamide construction with insulation class H provide robust, safe wiring and long-term reliability in industrial environments. Compatibility with model 9677.100 and 50–60 Hz operation ensures straightforward integration with existing NH assemblies and control panels, minimizing engineering effort and risk.
