It is a general-purpose variable-frequency drive in fan-cooled form factor, with the model code split into A=version type, B=B-series, 43=460V three-phase, and 300=40HP (30kW). Practically, a 30kW drive of this class targets induction-motor loads in the 25–30kW range — pumps, fans, conveyors, and compressors — where the 460V three-phase supply matches the motor nameplate and the panel bus is already at that voltage class. ## Overload, frequency control, and stall behaviour Overload endurance is rated at 150% of rated current for 1 minute, which is the figure to check against high-inertia starts or short-cycle peak loads rather than continuous running. Stall prevention is adjustable from 20% to 250% of rated current, giving the integrator headroom to tune the trip curve to the motor's actual breakdown torque instead of leaving it at the default. Frequency setting resolution is 0.01Hz, which is fine enough for process-speed trim on pumps and conveyors without a separate closed-loop encoder. Three skip-frequency zones are programmable across the 0.1–400Hz range, useful for steering the operating point off mechanical resonance bands common in fans and pump couplings. ## Thermal envelope and panel-side environment The unit is fan-cooled and rated for ambient humidity below 90% RH (non-condensing), so it fits a standard indoor control cabinet without a sealed enclosure — but the cabinet should still maintain clearance around the fan intake. Storage and transportation temperature spans -20°C to 60°C, which is the handling window during shipping and winter commissioning, not the running figure.","metaTitle":"Delta VFD300B43A AC Drive, 460V 3-phase, 40HP (30kW)","metaDescription":"Delta VFD300B43A — B-series 460V three-phase VFD rated 40HP (30kW), fan-cooled, 150% overload for 1 minute.
