This prevents contamination should the public drinking water system's pressure drop. vacuum breaker typically contains a plastic disc that is pressed forward by water supply pressure, and covers small vent holes.
10.1 Development of Vacuum Circuit breakers If the contact system of the vacuum circuit breaker is judged by mechanical construction it is the simplest of the arc interrupting systems, it consists, in principle, of only a fixed and movable contact located in a vacuum vessel.ACUUM CIRCUIT BREAKERS Learning objectives The student should be able to: 1. Understand the terminology of vacuum replacement. 2. Understand the technology of vacuum replacement breakers. 3.
