Enclosures can be either integrated or barrier formats. The Altivar 71 ac drive is designed for constant torque and heavy-duty applications at 150% current limit for motors from 1 to 40 hp at 208 to 230 V, and 1 to 450 hp at 460 V. The Altivar 61 operates variable-torque, light-duty motors with 110% current limit from 1 to 50 hp at 208 to 230 V and 1 to 500 hp at 460 V.
