Rittal SV9677.810 is a 150 A/5 A accuracy class 1 current transformer for inductive current measurement in compatible size 00 NH slimline fuse-switch disconnectors and switch-disconnectors within 185 mm systems.
£41.98
The Rittal SV9677.810 is a compact current transformer for NH slimline fuse-switch disconnectors and NH slimline switch-disconnectors, designed for inductive measurement of current flow in industrial low-voltage power distribution systems. It is specifically engineered for selected Rittal SV 9677XXX size 00 devices.
Featuring a 150 A primary current and 5 A secondary current, the SV9677.810 provides a standardised measurement signal for compatible metering and monitoring equipment. It offers accuracy class 1, a rated output of 2.5 VA and a rated frequency range of 50–60 Hz.
Its compact polyamide construction integrates mechanically into the mounting components of the 185 mm centre-to-centre system without altering the installation depth, supporting space-efficient panel layouts. Screw terminals provide the secondary electrical connection, with support for round conductors from 2.5–4 mm².
Current transformers allow high circuit currents to be represented by a lower secondary current that can be used by compatible measurement and monitoring equipment. With its 150 A / 5 A ratio and accuracy class 1 performance, the Rittal SV9677.810 provides a coordinated current measurement solution for selected size 00 NH slimline devices.
Mechanical integration into the 185 mm centre-distance mounting system enables the transformer to be installed without increasing the installation depth. This makes the SV9677.810 particularly useful in industrial switchgear where efficient use of enclosure space and straightforward integration of current measurement equipment are important.
