The NRC series is a new generation of flexible Rogowski coil current sensors (Rogowski® coil), which are especially suitable for measuring in combination with portable devices. NRC coils have different sizes to cope with different conductors. The new generation of NRC coil strengthens the shielding layer and greatly reduces the influence of external magnetic fields; it can be directly connected to our panel-type and rail-mounted meters without the need for external integrators. NRC series coils have an IP68 protection grade, which is extremely suitable for outdoor use.
