3-in-1 flexible Rogowski coil | 6000 A | 50 mV/kA | 2 m cable | RJ45 / RJ12 | NRC-200 coil model | STP-6K
Code: ESSTP-6K3-in-1 flexible Rogowski coil designed for current measurement in three-phase electrical systems up to 6000 A. One set integrates three flexible NRC-200 type Rogowski coils, allowing safe, fast, and non-intrusive installation around large-diameter conductors or busbars without disconnecting power. Thanks to the large internal diameter (200 mm), high accuracy, and 85 mV/kA output signal, this coil is ideal for industrial switchboards, substations, generators, transformers, and high-power lines where traditional CT solutions become impractical.
