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 This part is obsolete per the manufacturer.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.","metaTitle":"Schneider Altivar VW3A7790 Braking Resistor, 6.7 Ohm, 20 kW,","metaDescription":"Obsolete Schneider Altivar VW3A7790 braking resistor. 6.7 Ohm, 20 kW at 40 °C, IP23.
