Schaffner's FN 5060 HV 690/600 VAC filter is available with current ratings from 16 A to 1’200 A.

 690/600 VAC filter SchaffnerSchaffner’s introduced its FN 5060 HV standard dv/dt filter series, designed for 690/600VAC motor applications. The filters enable dv/dt filter damping performance without using resistors or capacitors. Motor drive output filters protect motor windings against excessive voltage peaks and inadmissible voltage pulse rise times generated by the inverter PWM output voltage. Dv/dt filters are required to fulfill the IEC 60034-17/-25 standards defining the limits for IEC-and NEMA AC-motors and prolonging their life times. The standard 690/600 VAC filter series are available with current ratings from 16A to 1200A. Higher or other ratings can be engineered and delivered on demand. All models are CE, UL, CSA and ENEC approved and RoHS compliant. Not only to be used in areas where pumps and fans are controlled by drives with short motor cables, the dv/dt filters are also recommended to be used for applications with frequent braking, danger of flash-over voltage and motors running at high temperature.
