It operates on 380–415 V supplies and draws a recommended 350 A fuse at 660 V, which sets the upstream protection size for the branch circuit supplying the braking module. Overload protection is set at 1.2× the maximum current — the unit will hold that margin before tripping, so the drive's braking chopper threshold should be coordinated below this ceiling. ## Panel fit and environmental limits The enclosure measures 837 mm high × 380 mm wide × 395 mm deep at IP20 — this is a floor-standing or large panel-mount footprint, not a DIN-rail module; plan for bottom cable entry and top ventilation clearance. Rated efficiency is 97 % with a power factor of 1 (cos phi = 1), meaning the braking unit draws near-unity current from the DC bus with minimal reactive component. Operating altitude is 1000–4000 m with a 5 % current derating per additional 1000 m above sea level — installations above 1000 m must reduce the braking current proportionally to stay within the thermal envelope. Storage temperature range is -25 to 55 °C; the unit can sit in an unheated warehouse or shipping container within that band without damage. ## Obsolete — sourcing through independent channels Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or form-fit-function replacement is documented by Schneider, so a substitution requires a full braking-unit selection review against the drive's DC bus voltage and braking duty cycle.","metaTitle":"Schneider VW3A7209 Network Braking Unit, 160 kW, 400 V","metaDescription":"Schneider Electric VW3A7209 network braking unit, 160 kW at 400 V for variable speed drives.
