Product details

The Schneider VW3A4512 is a DC choke rated at 195 A with 0.09 mH inductance, designed to reduce current harmonics on the DC bus of a variable speed drive. 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.

Frequently asked questions

Where can I buy VW3A4512?

We can source it to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time — submit an RFQ for the latest position.

What are the key ratings for VW3A4512?

Rated current is 195 A DC, inductance is 0.09 mH, thermal losses are 73 W. It operates on a 3-phase 50...60 Hz supply and measures 280 x 240 x 191 mm.

What is VW3A4512's depth?

The depth is 240 mm. Combined with the 280 mm width and 191 mm height, you need a panel at least 300 mm deep to allow wiring clearance behind the choke.
