Flexible rogowski coil – MRC Series – 100A to 600A

Category: Tag:

20,00 

The MRC series is a new generation of flexible Rogowski coil (Rogowski® coil) current sensors, which are especially suitable for measuring in combination with portable devices. MRC coils have different sizes to cope with different conductors. The new generation of MRC coil strengthens the shielding layer and greatly reduces the influence of external magnetic fields; it can be directly connected to our rail-mounted and panel-type meters without the need for external integrators. MRC series coils have IP67 protection grade.
