Product Details
40.5 kV Embedded Pole — 1250 / 1600 A
An embedded pole for vacuum circuit breaker assembly, with conductor construction, mounting datums and drive interfaces matched to the selected configuration.
Technical Description
This embedded pole is intended for a matched vacuum circuit breaker assembly. Select the current configuration using its conductor construction and drawing reference. Check terminal connections, mounting datums, phase arrangement and the operating mechanism before selection. A current option does not establish that the same physical pole serves both configurations. Define the supplied pole assembly and accessories, with insulation, partial discharge and interruption data tied to the selected version.
