The R Series Filters come in single-phase and three-phase versions and feature several connection options. The current ratings for the single-phase units range from 0.5 A to 300 A with line voltages up to 250 VAC or 250 VDC and leakage currents of 1 mA. Low leakage models are available with 10 µA of leakage current at 250 VAC, 60 Hz. The three-phase filters have current ratings from 6 A to 1,000 A with line voltages up to 500 VAC or 500 VDC. The maximum leakage current is 2.5 mA at 250 VAC and 60 Hz or 5 mA at 500 VAC, 60 Hz. The operating temperature range is -25°C to +85°C.
