Drive selection memo — 3ABD50000039004
The ABB 3ABD50000039004 is a wall-mounted LV AC drive rated 5.5 kW normal-use output at 12.6 A, with a heavy-duty rating of 4 kW at 9.4 A. Input accepts 380-500 V three-phase at 47.5-63 Hz.
Rating breakdown — normal vs heavy duty
Two current ratings govern the load match: 12.6 A normal use (5.5 kW) for constant-torque fans and pumps, and 9.4 A heavy duty (4 kW) for higher starting torque or cyclic loads. Light-overload use is rated 12 A (5.5 kW), essentially matching normal duty.
No additional enclosure needed for most indoor washdown or dusty mill environments — saves panel space and cooling design. Wall-mounting is assumed; no separate mounting bracket required.
