RRC-RJ11 — flexible Rogowski coil for Milesight CTH01
Milesight RRC-RJ11 is a Rogowski coil designed to measure high AC current values up to 4000 A. The accessory works with the Milesight CTH01 Smart Power Monitor Hub.
The flexible coil design enables it to fit around large conductors, power cables and busbars where conventional rigid-core current transformers may be insufficient.
The RJ11 connection enables quick connection of the coil directly to one of the CTH01 current channels.
Up to 4000 A, Ø150 mm and quick RJ11 connection
4000 A
The wide measurement range enables monitoring of circuits with very high current values.
Ø150 mm
The large measurement opening facilitates installation around large conductors and busbars.
RJ11
Direct connection to CTH01 current channels simplifies system installation and configuration.
Monitoring high-load installations
Range from 0 to 4000 A
RRC-RJ11 is designed to measure high current values in installations where the range of conventional 100 A, 300 A, 500 A or 1000 A current transformers is insufficient.
Measurement opening Ø150 mm
The Rogowski coil design enables installation around large and irregular conductors, including power cables and busbars.
The 150 mm diameter opening provides significantly more installation space than conventional current transformers available for CTH01.
Direct connection to an RJ11 current channel
RRC-RJ11 is designed as a measurement accessory for the Milesight CTH01 Smart Power Monitor Hub.
CTH01 has 12 current measurement channels with an RJ11 interface and supports both conventional current transformers and Rogowski coils.
After the sensor is connected, the hub uses its measurement to calculate energy parameters of the monitored circuit.
Input data for advanced CTH01 measurements
Combined with CTH01, current measurement from RRC-RJ11 can be used to analyze RMS current, power, energy and power factor, among other parameters.
CTH01 also supports analysis of power quality parameters such as THDi, as well as measurement of active, reactive and apparent power and energy.
Flexible use in single- and three-phase installations
CTH01 enables independent use of 12 current channels or grouping them into three-phase circuits.
Current transformers and Rogowski coils can be used in one CTH01, but the same sensor type must be maintained within one measurement group.
Installation without disconnecting the measured conductor
The opening and flexible coil design allows the measured conductor to be enclosed without cutting it or routing it through a closed transformer core.
During installation, the correct measurement direction must be maintained and the conductor must be properly positioned inside the loop.
CTH01 enables software correction of measurement direction, making it easier to correct a polarity error without repositioning the sensor.
