The VFD037B43A is a Delta B Series variable-frequency drive rated for 5 HP (3.7 kW) on a 460V three-phase input. It delivers 150% of rated current for 1 minute — that's the overload endurance for starting a loaded conveyor or pump without nuisance tripping. Frequency resolution is 0.01 Hz, which gives fine speed control for applications like metering pumps or winding drives where tight speed regulation matters. The drive includes three programmable skip-frequency zones covering 0.1 to 400 Hz, useful for avoiding mechanical resonance in fans or spindle motors.
