Westinghouse IQ-1000 II Variable Frequency Inverter. 1991 Westinghouse Ampgard Motor Starter Control Panel. Cat. No: AT-10420-L10-H. Order No: 11-202 50J4. Dwg: 3D53105, 3D53105, 3D52103. Power supply (bottom): 700 HP, 4160v, 60 Hz. Each Ampgard motor starter (controller) consists of one non load-break isolating switch, one or more Type SLS vacuum-break contactors, current-limiting fuses, a set of current transformers, and overload protection. The controller is designed to start, stop and protect a three-phase medium-voltage motor or may also be used to switch transformer windings or other medium voltage loads. These controllers are configured for full-voltage applications. Westinghouse IQ-2000 Variable Frequency Inverter provides complete circuitry protection against abnormal operations such as overload, inductive type loads, short-circuit, and AC Input Over-Voltage. Overall dimensions: 37 in. L x 37 in. W x 99 in. H.
