Westinghouse Ampgard Medium Voltage Motor Starter Control Panel. Ref. No's: AT-72980-1 and V20254G. Power supply: 300 HP, 4160v, 38 FLA, 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 some form of 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 35 in. W x 103 in. H.(H11).
