Product Details
40.5 kV Embedded Pole — 2000 / 2500 A
An embedded pole for vacuum circuit breaker assembly, selected by terminal construction, installation space, thermal conditions and mechanism compatibility.
Technical Description
This embedded pole combines vacuum interruption components with an insulating structure. Assess its terminals, installation space, thermal conditions and mechanism compatibility using its own drawing. Current options must be linked to a defined conductor configuration. Specify whether external busbars, connection pieces or the operating mechanism are included with the pole. Insulation test data must identify the test locations and conditions for the selected assembly.
