Quick Summary
SV current transformer 9677.885 provides inductive current measurement for NH slimline fuse-switch disconnector installations. Engineers often confront installation depth and space constraints in compact control panels, and this unit delivers a space-saving integration by fitting into top-mounting components without increasing depth. It complies with IEC 60 044-1 testing and uses insulation class H between conductors and housing, supporting reliable operation at 50–60 Hz. With a 600 A primary and 5 A secondary, plus 2.5 VA rated power input, the design enables precise metering while keeping panel footprints small, reducing cabling complexity and total cost of ownership.

FAQs
The SV 9677.885 is designed for NH slimline fuse-switch disconnector size 3 and integrates without increasing installation depth. It features 185 mm centre-to-centre spacing and a top-mounting design that simplifies mounting within compact panels, reducing complexity during installation and enabling faster commissioning.
Key specs include a 600 A primary current, 5 A secondary current, 2.5 VA rated power input, and operation at 50–60 Hz. The device uses a box-terminal connection and insulation class H, with an accuracy class of 1, suitable for precise current measurement in high-current circuits.
The data confirms conformity to IEC 60 044-1 test specifications and insulation class H, which supports regulatory compliance in many regions. While CE marking is not explicitly listed, the product’s safety and performance characteristics align with standard electrical measurement components used in certified panels.
The compact design allows space-saving integration inside NH slimline assemblies, with no alteration to installation depth and a fixed 185 mm center-to-center spacing. This reduces panel footprint, accelerates installation, and simplifies future upgrades or expansions in modular switchgear configurations.
With a robust polyamide housing, box-terminal wiring for 2.5–4 mm² conductors, and a straightforward top-mount installation, wiring errors and rework are minimized. The result is lower maintenance costs, faster commissioning, and improved uptime, contributing to a faster return on investment in high-current distribution panels.
