Yaskawa GA50U4012ABA GA500 Variable Frequency Drive

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.

Technical Specifications

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.
