It's an Altivar-series accessory, sized for a 3-phase supply at 50...60 Hz. The 195 A rating is the continuous DC current the choke is built for. That's the number you match to your drive's DC bus rating — oversizing by more than a step wastes panel space and copper. The 0.09 mH inductance is fixed; it's not adjustable, so verify it's the right value for your drive's harmonic profile. Temperature derating is real here. Full rated current is good from -10 °C to 50 °C ambient. Above 50 °C up to 60 °C, you derate 2.2 % per °C. So at 55 °C ambient, you're down to about 89 % of 195 A — roughly 174 A continuous. Plan your enclosure cooling around that. Altitude derating kicks in above 1000 m: 1 % per 100 m. At 2000 m, that's 10 % off the current rating. If your site is in Denver or Mexico City, factor that in. The power supply connection uses bare wires up to 9 mm diameter — that's a substantial lug, so make sure your ring terminals or bus bars fit. Physical footprint: 280 mm wide, 240 mm deep, 191 mm tall. That's a decent chunk of panel real estate. The depth of 240 mm means it won't fit in a shallow 200 mm enclosure — you'll need at least a 300 mm deep cabinet to leave room for wiring behind it.","metaTitle":"Schneider VW3A4512 DC Choke, 195 A, 0.09 mH, Obsolete","metaDescription":"Schneider VW3A4512 DC choke, 195 A rated current, 0.09 mH inductance, 73 W thermal loss.
