Part description

Product description
The Rogowski coil RCMA-B22-DXX is intended for the electronic measurement of alternating current.
The Rogowski coil must only be used in conjunction with a Weidmüller transducer RCMC-5000-XX.

Functional description
The primary circuit (power circuit) and the secondary circuit (measurement circuit) are galvanically isolated by the Rogowski coil.
As there is no saturation effect, currents can be measured over a wide primary current range without any losses in accuracy.

Features
  • Conductor diameter of the measuring coil: 6.1 mm
  • Housing tabs for attachment with cable ties
  • Sealable bayonet fastening
