With 5-limb body, Series CNW 910 and CNW MC 835 are indispensable to electromagnetic compatibility of entire system. Units can be used as 3-phase network chokes or motor chokes, and in standard version are dimensional for nominal currents up to 1,200 A. Additional unwound limb ensures chokes are able to both transmit and damp common-mode noise until such time as it can be ultimately conducted to earth.
