Product Overview
The Yaskawa GA50U4012ABA is a GA500 series industrial variable frequency drive for 380 to 480 VAC three-phase motor systems. It provides a 7.5 HP or 5.5 kW Normal Duty rating with 11.9 A output current. For applications requiring increased overload capability, it provides a 5 HP or 3.7 kW Heavy Duty rating with 9.2 A output current.
The difference between its Normal Duty and Heavy Duty ratings is important during drive selection. Normal Duty is generally suitable for variable-torque and moderate-overload loads, while Heavy Duty should be considered for machinery with higher starting torque, repeated acceleration or more demanding load cycles.

Compatible System and Applications
This drive can be used with conveyors, pumps, fans, compressors, packaging machines, material-handling systems, mixers and other industrial equipment. The correct duty rating depends on motor full-load current, starting torque, acceleration time and the machine operating cycle.
Maintenance and Replacement Notes
Do not select GA50U4012ABA only by its 7.5 HP Normal Duty rating. Confirm whether the installed application requires Normal Duty or Heavy Duty operation. Check the complete model, nameplate specification, supply voltage, motor current, control wiring, braking arrangement, safety circuit, communication network and parameter configuration before replacement.
Related Models
GA50U4009ABA is the adjacent lower-current model, while GA50U4018ABA provides a higher output range. GA50U4005ABA and GA50U4007ABA are alternatives for smaller motors within the GA500 480 V family.
Inquiry and Supply Notes
Please send the complete drive nameplate, motor data and application information for technical confirmation. Communication options, braking resistors and external enclosure components should be specified separately. Price and delivery time require confirmation before purchase.
