Selection Notes

The VW3A7105 covers the 110-160 kW Altivar Process ATV900 drives, sized for 100 kW permanent braking power with a 160 kW maximum at a load factor of 1 and a 2.5 Ohm minimum resistor value. Its IP21-top enclosure and forced cooling (166 m3/h) distinguish it from the smaller natural-convection braking accessories in the range, and the 780 V DC activation threshold matches the ATV900's DC bus. Pair it only with drives in this power class; larger ATV900 frames need a higher permanent-power braking unit in the same accessory line.
