Rittal SV9677.840 is a compact 200 A/5 A accuracy class 1 current transformer with 1.5 VA rated output for compatible size 1–3 NH slimline fuse-switch disconnectors in 185 mm power distribution systems.
£62.92
The Rittal SV9677.840 is a compact current transformer for NH slimline fuse-switch disconnectors, designed for inductive measurement of current flow in industrial low-voltage power distribution systems. It is engineered for selected Rittal SV 9677XXX size 1–3 devices within the 185 mm busbar system.
Featuring a 200 A primary current and 5 A secondary current, the SV9677.840 provides a standard measurement signal for compatible metering and monitoring equipment. It offers accuracy class 1, a rated output of 1.5 VA and a rated frequency range of 50–60 Hz, making it suitable for current monitoring in professional power distribution assemblies.
The compact polyamide transformer integrates mechanically into the top mounting components of the 185 mm centre-to-centre system without increasing the installation depth. Electrical connection is provided by an integrated 2.5 mm² round conductor with a length of 1.5 m, helping simplify installation within space-conscious switchgear designs.
Current transformers allow the current flowing through a power circuit to be represented by a lower secondary current suitable for compatible meters and monitoring equipment. With its 200 A / 5 A ratio, 1.5 VA rated output and accuracy class 1 performance, the Rittal SV9677.840 provides a coordinated measurement solution for selected NH size 1–3 fuse-switch disconnectors.
Mechanical integration into the top mounting components of the 185 mm centre-distance system allows the transformer to be incorporated without altering the installation depth. This space-saving arrangement makes the SV9677.840 particularly suitable for industrial switchgear where efficient enclosure utilisation and integrated current monitoring are required.
