Westinghouse Ampgard Medium Voltage Motor Starter Control Panel. (2) units: 1000 HP and 700 HP, 4160 V, 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: 3ft. 1in. L x 3 ft. W x 8 ft. 2 in. H.
