Quick Summary
Rittal SV 9677.810 Current Transformer measures current inductively in NH slimline fuse-switch disconnector assemblies. Engineers often struggle with space constraints and installation depth when adding metering in compact control panels. The device aligns with IEC 60 044-1 test standards, supports 50–60 Hz operation, insulation class E, and an accuracy class of 1. This combination minimizes wiring complexity and enables reliable monitoring. By integrating into top-mount components using 185 mm centre-to-centre spacing, it delivers space-saving benefits while maintaining robust performance in industrial environments. With 150 A primary and 5 A secondary, a 2.5 VA burden, and a box-terminal connection, it supports protection relays and metering without sacrificing panel density.

FAQs
Install the SV 9677.810 by inserting it into the NH slimline top-mount area and securing the box-terminal connections. Use conductor sizes 2.5–4 mm² and align with the 185 mm centre-to-centre spacing for precise fit within size 00 modules. Ensure the unit operates at 50–60 Hz and verify proper insulation class E handling.
Yes. The transformer is specified for a 150 A primary and a 5 A secondary, with a burden of 2.5 VA, providing reliable inductive current measurement for protection relays and metering circuits while keeping measurement error within Class 1.
Ideal for motor control centers and panel boards that require compact, accurate current measurement without increasing installation depth. It integrates into NH slimline assemblies, enabling space-saving metering for protection relays and energy monitoring while maintaining standard wiring practices.
The device conforms to the IEC 60 044-1 test specification and uses insulation class E. It also aligns with ETIM EC002048 and ECLASS 27141146 classifications, ensuring compatibility with standardized data models and procurement processes.
Benefits include reduced panel depth requirements and wiring complexity, faster installation, and reliable current measurement (150 A/5 A) with Class 1 accuracy. The compact design lowers labelling and maintenance costs while improving panel density and overall system reliability.
