FAQs
Yes. The SV 9677.875 is designed for NH slimline fuse-switch disconnector size 2-3, featuring a compact profile and 185 mm centre-to-centre spacing that preserves installation depth while enabling straightforward top-mount integration. Use the box-terminal connection for 2.5–4 mm² conductors to ensure reliable wiring and consistent sensing.
Key specs include a 400 A primary current and 5 A secondary current, with an accuracy class of 1. The device supports a rated frequency of 50–60 Hz and a rated power input of 2.5 VA. It uses a box-terminal connection and insulation class B, making it suitable for typical industrial distribution and protection tasks.
The transformer is tested to IEC 60 044-1 standards, with insulation class B, and a defined 50–60 Hz operating range. While CE marking and IP ratings are common, the provided data explicitly references IEC 60 044-1 and insulation/class ratings; confirm local compliance requirements with purchasing for your region.
The design supports space-saving, top-mount integration without altering installation depth, reducing assembly time. Its 2.5 VA power draw and 185 mm spacing aid efficient wiring layouts, while the box-terminal connection simplifies field wiring and reduces termination errors in dense control panels.
By providing stable, accurate current sensing (1A class), the SV 9677.875 minimizes nuisance trips and improves protection reliability. Its compact form and robust wiring reduce installation and maintenance costs, enabling faster panel builds and longer service intervals in high-demand environments.
