It dissipates regenerative energy from a variable-speed drive's DC bus as heat through an external resistor, preventing overvoltage trips during deceleration or overhauling loads. Efficiency sits at 97 % with a unity power factor (cos phi = 1), meaning nearly all the braking energy drawn from the bus is converted to heat with minimal electrical loss. The unit includes built-in overload protection at 1.2× the maximum current, so it can handle short-duration overloads above the continuous rating without nuisance tripping. The enclosure measures 295 mm deep, 270 mm wide, and 500 mm high, with an IP20 rating — suitable for installation inside a ventilated electrical enclosure where tools are required for access. Mounting provisions match the standard footprint for Schneider's Altivar drive family braking accessories; verify panel cut-out and clearance against the 500 mm height before committing the layout. A 20 A fuse at 660 V is specified for branch-circuit protection. Operating altitude is 1000 to 4000 m with a current derating of 5 % per 1000 m above 1000 m — factor this into the thermal design if the cabinet sits above 1000 m elevation.","metaTitle":"Schneider VW3A7201 Braking Unit 7kW 400V, Obsolete","metaDescription":"Schneider VW3A7201 network braking unit, 7 kW, 400 V, for variable speed drives.
