Product details

The Schneider Altivar VW3A7816 is a braking resistor for the Altivar drive family, rated 0.7 Ohm and 225 kW at 50 °C. It dissipates regenerative energy from decelerating motors as heat, preventing DC-bus overvoltage trips on the drive. The M10 bar connection handles the high current without terminal overheating.

The enclosure measures 820 mm deep, 1140 mm wide, and 1150 mm high — a substantial floor-mounted cabinet, not a DIN-rail component. IP23 protection means it sheds dripping water at up to 60° from vertical but is not washdown-rated; install in a sheltered indoor location. Ambient operating range is 0 to 50 °C; storage from -25 to 65 °C.

Frequently asked questions

How do I get current pricing and availability for VW3A7816?

Submit an RFQ. We source this obsolete resistor through independent distribution and confirm availability and current pricing at quote time.

What is VW3A7816's power rating?

225 kW at 50 °C ambient. That is the continuous dissipation capacity before thermal overload protection (via an external thermal overload relay) engages.
