Medium-Voltage Solid-State Reduced Voltage Controllers (SSRVC), Type Series 81000™

Up to 15 kV 300 A

Features and Benefits

Description

Solid-state reduced-controllers consist of a main contactor, SCR chassis and a line-start rated bypass contactor. The SSRV starter provides the most flexible starting options, offering selectable current or voltage ramps. For emergency full-voltage starting, the bypass contactor can be used as an across-the-line starter by changing a control switch position. As an option, the starter can be equipped with a permanent emergency across-the-line starting option including an additional set of current transformers, normal/emergency selectro switch and a bi-metal overload relay. Repositioning power cables for this option is not required.
