Manufacturer source discovery; confirm the exact regional equipment configuration and certification separately. Use the manufacturer configuration named Thermal overload relay LR9G 500A Spring. ## In plain English ### What the equipment does Overload protection responds when a motor is carrying excessive current for too long or heating beyond its configured limit. It can request that the motor is stopped. ### A simple example Use LR9G500_3D-simplified.stp (revision 01) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified LR9G500_3D-simplified.stp. ### What the drawings help you do Use LR9G500_3D-simplified.stp (revision 01) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified LR9G500_3D-simplified.stp. ### Before using this reference - Match Schneider Electric Thermal overload relay LR9G 500A Spring and the exact source filename shown above. - The supplied model has approximate X × Y × Z bounds of 140 × 114.3 × 139.2 mm.
