- Description
The ABB 2CSG202150R1101 (R4M-200) is a flexible Rogowski-coil current transformer with a 200 mm bore diameter and 3 m lead length, rated for a 10000 A primary current. It comes with pre-wired removable terminals for direct connection to M4M 20 and M4M 30 Rogowski energy meters, letting it wrap around large busbars or cable bundles that a rigid split-core CT cannot fit around.

Selection Notes
A 200 mm bore fits around larger busbars, multi-cable bundles or high-current feeders that the 80 mm R4M variant cannot physically encircle. The flexible Rogowski design lets it be looped and closed around a conductor without disconnecting it first, unlike a rigid split-core CT of the same current range. Pre-wired removable terminals plug directly into M4M 20 and M4M 30 Rogowski meter inputs, so no separate termination kit is needed.
