Sizing for the load
Normal-use 169 A suits variable-torque HVAC fans and centrifugal pumps. Light-overload rating at 161 A splits the difference for cyclic loads. Pick the duty column that matches your motor nameplate and application profile.
Wall-mount, IP21 / NEMA Type 1. R6 frame. Plan for top and bottom cable entry clearance. Ambient temperature derating applies above 40 °C — check the drive's thermal curve. No gland plate included; order separately if needed.
Sourcing posture
Active, current lifecycle stage. No last-time-buy window or successor announced. Frame R6 is a common size; if a swap is urgent, the heavy-duty current column (145 A) is the conservative fit for an unknown load.
