Why Choose the ABB RC120-15 Current Sensor?
The ABB RC120-15, order code 1SFA664005R1215, is an open-loop Rogowski coil current sensor designed for use with the ABB CSU-2LV current sensing unit as part of the Arc Guard System. It provides current measurement for low-voltage applications, enabling the CSU-2LV to use current information alongside optical arc detection for enhanced arc-flash protection.
The RC120-15 uses Rogowski coil technology to measure current around a busbar or cable without requiring a conventional iron-core current transformer. It is specifically designed for the CSU-2LV and provides a measurement output of 0.361 V/kA, with connection to the current sensing unit through an RJ45 connector.
With a 120 mm coil diameter and a 15 m cable length, the RC120-15 provides considerable flexibility for installation around conductors and busbars within low-voltage switchgear. The sensor incorporates a 12.4 mm transducer diameter, uses a bayonet holder for the open-loop coil and is designed to operate across temperatures from -30 to +80 °C.

Current Measurement for Enhanced Arc-Flash Protection
The ABB CSU-2LV current sensing unit can use current information in combination with optical arc detection to enhance the selectivity and reliability of an Arc Guard installation. The RC120-15 measures current using a Rogowski coil positioned around the relevant low-voltage conductor or busbar and provides the measurement signal required by the CSU-2LV.
The open-loop construction simplifies installation because the coil can be fitted around an existing conductor without requiring the conductor to be passed through a permanently closed sensor. Its 120 mm internal coil diameter and 15 m cable make the RC120-15 particularly suitable for larger switchgear assemblies where the sensor and CSU-2LV may need to be installed some distance apart.
Typical Applications
- ABB CSU-2LV current sensing installations.
- ABB Arc Guard arc-flash protection systems.
- Low-voltage switchgear and switchboards.
- Current measurement around electrical busbars.
- Industrial power distribution systems.
- Motor control centres and low-voltage electrical assemblies.
