What the ratings mean for your drive line
The dual voltage-power rating tells you this filter is sized for specific SINAMICS drive frames. The 500-600V band at 250/315 kW suits medium-voltage drives in that power class; the 660-690V band at 400/450 kW covers the higher-voltage, higher-power range. Both operate at 50/60 Hz, so the filter works globally. The 'low-frequency line harmonics' reduction targets the 5th, 7th, 11th, and 13th harmonics typical of 6-pulse rectifier drives — cleaning up the line-side current waveform to meet IEEE 519 or local grid codes without adding a separate active filter.
Sourcing reality
Because this is a made-to-order class D product, it's not sitting on a shelf. Each unit is quoted and built to the customer's specifications. Submit an RFQ with your drive model and required power rating — the engineering team will confirm the exact configuration and lead time. Availability and current pricing are confirmed at quote time.
