Product details

The Schneider Electric VW3A7709 is a braking resistor for the Altivar 61 drive series, rated at 2.5 Ohm with 1 kW average power available at 50 °C. It dissipates regenerative energy from decelerating motor loads — typical for conveyors, centrifuges, or any application where the drive must stop quickly or hold a vertical load. The resistor body carries IP20 protection, so it mounts inside the drive enclosure or a separate ventilated cabinet, not in a washdown zone.

Physical integration

The resistor measures 484 mm high, 240 mm wide, and 301 mm deep — a substantial block that needs clear air space around it. Mount it vertically with the terminals at the bottom so natural convection carries heat upward.

Frequently asked questions

Where can I buy VW3A7709 and get a price?

We source VW3A7709 to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time estimate.

What is the closest alternative to VW3A7709?

No pin-compatible or form-fit replacement is published by the manufacturer. A parametric match requires a 2.5 Ohm, 1 kW braking resistor with the same M6 bar connection and thermal switch interface, but dimensions and mounting will differ. Verify the drive's braking chopper rating and available cabinet space before substituting.

What are the physical dimensions of VW3A7709?

The resistor measures 484 mm high, 240 mm wide, and 301 mm deep.

What compliance documentation does Schneider provide for VW3A7709?

The evidence does not list specific compliance certificates (RoHS, REACH, UL, IEC) for this order code. As an obsolete part, original documentation may be limited; request any available declarations at quote time.
