Motor Choke CNW M 854

Fully encapsulated three-phase motor choke

Voltage rise (<200V / us) and distortion reduce – protect electrical consumers optimally.

Motor chokes in fully encapsulated version are specially designed for rough environments and offer a very good mechanical protection of the component. The fully encapsulation allows design up to protection ratings IP 66.

Losses and heating are minimized and the leakage current reduced. Longer motor cable lengths are possible. By limiting the rate of voltage rise, the motor insulation is protected and thus prolongs the life. The motor choke also attenuates the conducted interference in lower frequency range very good. The losses and the typical noise in the motor plate can be reduced. Voltage rise (<200V / us) will be reduced.

Increasing the service life of motors, reduction of edge steepness dv/dt to earth and between phases, reduce motor noise, current smoothing.
