Drive module for HVAC — frame R11, 302 A
The ABB 3AXD50000507917 is a low-voltage AC drive module from the ACH580-34 series, purpose-built for HVAC applications where harmonic mitigation is required. It carries UL ratings at 480 V: 302 A in light-overload duty (250 Hp) and 240 A in heavy-duty use (200 Hp). The frame size is R11, a module-style package that mounts into a larger drive cabinet or panel.
UL ratings and duty selection
The two UL current ratings define the load envelope. Light-overload (302 A) suits variable-torque loads like fans and centrifugal pumps where peak demand is intermittent. Heavy-duty (240 A) covers constant-torque loads such as conveyors or positive-displacement pumps, or applications requiring higher overload margin. The 480 V input aligns with North American distribution voltages.
