Westinghouse Ampgard Medium Voltage Motor Starter Control Panel. Ref. No's: TA-50685-1, V202 K4G, AT-10420-L10-4 and U-202-5J04. Dwg: TA685 S1L, TA685 W1L, 3D53104, 3D53105 and 3D53103. Power supply: 1000 HP and 300 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 98 in. H.
