Medium voltage circuit breakers

SIMPLIFIED DRAW- OUT FOR THREE – PHASE VACUUM CIRCUIT BREAKER - ESD – MT

General characteristics

The simplified draw-out for three-phase vacuum circuit breakers that it was developed to assist the recommendations of the cubicles Metal Enclosed standards. It is a maneuver equipment used in three-phase distributuion systems, capable to interrupt or to establish the electric continuity in panels.

This equipment was developed to assist manufacturers of panels that don't possess technology of draw-out vacuum circuit breakers, facilitating the opening / closing electric circuits operation with safety, through the manual and / or motorized operation.
