Why Choose the ABB RC200-30 Current Sensor?
The ABB RC200-30, order code 1SFA664005R2030, is an open-loop Rogowski coil current sensor designed for use with the ABB CSU-2LV Current Sensing Unit in low-voltage Arc Guard applications. It provides current measurement for systems where current is used alongside optical detection as part of the arc-flash protection logic.
The RC200-30 features a large 200 mm coil diameter, making it suitable for installation around substantial busbars and power cables. Its open-loop construction with bayonet holder supports convenient installation, while the extended 30 m connection cable provides excellent flexibility where the CSU-2LV is positioned remotely from the monitored conductor.
Using Rogowski coil technology, the RC200-30 provides a measurement output of 0.361 V/kA and connects to the compatible CSU-2LV using an RJ45 connector. With a transducer diameter of 12.4 mm and an operating temperature range of -30 to +80 °C, it is designed for demanding low-voltage switchgear and industrial power distribution applications.

Reliable Current Measurement for Arc-Flash Protection
ABB Arc Guard systems can combine rapid optical arc detection with current measurement to improve protection selectivity. The RC200-30 supplies current measurement information to the CSU-2LV, allowing an overcurrent condition to be evaluated alongside detected arc light as part of a coordinated arc-flash protection system.
Rogowski coil technology is well suited to high-current low-voltage installations because the open-loop sensor can be fitted around an appropriate existing conductor without the closed magnetic core used by a conventional current transformer. The RC200-30 combines a 200 mm coil diameter with an extended 30 m connection cable, making it particularly useful in large switchgear assemblies where the sensing point and CSU-2LV are separated by a significant distance.
Typical Applications
- ABB TVOC-2 and CSU-2 Arc Guard protection systems.
- Low-voltage switchgear and switchboards.
- Current monitoring of large busbars and power cables.
- Motor control centres.
- Industrial electrical distribution systems.
- Arc-flash protection systems using combined optical and current detection.
