Product details

The Schneider Altivar VW3A7790 is a braking resistor for Altivar drives, rated 20 kW at 40 °C with a resistance of 6.7 Ohm. It provides medium-cycle braking with up to 120 % braking torque for a 120 s cycle, including <15 s braking intervals. The IP23 enclosure suits indoor panel mounting where some airflow is acceptable.

This part is obsolete per the manufacturer.

Physical integration

Dimensions are 1060 mm wide × 565 mm high × 540 mm deep. Electrical connection is via M10 terminals. The IP23 rating means it resists solid objects larger than 12 mm and water spray up to 60° from vertical — suitable for a ventilated electrical room but not for washdown environments.

Frequently asked questions

Where can I buy VW3A7790 and how do I get a price?

This obsolete braking resistor is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is the closest alternative to VW3A7790?

No official successor order code is listed by the manufacturer. A parametric match would need to match the 6.7 Ohm resistance, 20 kW power at 40 °C, and medium-cycle duty profile; consult with a sourcing specialist to identify a suitable replacement.

What are the physical dimensions of VW3A7790?

The VW3A7790 measures 1060 mm wide × 565 mm high × 540 mm deep.

What compliance documentation does Schneider provide for VW3A7790?

The evidence does not list specific compliance documentation (RoHS, REACH, UL, IEC) for this part. Verify documentation requirements at quote time.
