Milesight RRC-RJ11 | 4000A Rogowski Coil for CTH01

The Milesight RRC-RJ11 is a flexible Rogowski coil for the CTH01 Smart Power Monitor Hub, rated up to 4000 A. Its slim, flexible loop wraps around large conductors and busbars that rigid split-core CTs cannot fit. Lightweight at around 115 g with a 150 mm aperture, it connects to the CTH01 via an RJ11 lead for high-current energy and power-quality monitoring. Key Features High-Current SensingMeasures up to 4000 A, ideal for main feeders, risers and busbars. Flexible 150 mm ApertureA flexible coil fits around large or hard-to-reach conductors where a rigid CT won't. Lightweight & EasyAbout 115 g, simply wrap it around the conductor and plug into the CTH01. Plug-and-Play RJ11Connects directly to a CTH01 current channel via an RJ11 lead.
