- Description
The ABB 2CSG202160R1101 (R4M-80) is a flexible Rogowski-coil current transformer with an 80 mm bore diameter and 3 m lead length, rated for a 10000 A primary current. It ships with pre-wired removable terminals for direct connection to M4M 20 and M4M 30 Rogowski energy meters, suited to smaller busbars and individual cable runs where a bulkier coil will not fit.

Selection Notes
An 80 mm bore targets single cables or small busbar sections, where the 200 mm variant's larger loop would be unnecessarily bulky to route and secure. The same flexible Rogowski construction lets it close around a conductor without opening the circuit, and it shares the same pre-wired removable terminal and M4M meter compatibility as the larger-bore coil. At 0.15 kg it is noticeably lighter than the 200 mm version, easing routing in tight panel space.
