Thanks to the electromagnetic field created by this special contact design, it is removed from the cutting environment in a short time at the time of cutting. Contacts produced with powder metal technology reduce contact wear and extend contact life. With increased contact life, vacuum circuit breakers can break the short circuit current 100 times. The production of vacuum bottles, which are the products of advanced technology, is carried out in the 1000 class Clean Room. Vacuum flasks are sealed with vacuum brazing under vacuum at a vacuum level of 10-6mbar throughout their life. With the original design of the vacuum flask, there is no additional sticking point for the metal screen. The low number of connections increases the isolation level and reduces the possibility of leakage. Thanks to this design, SF6 gas, silicone, foam etc. No additional material is required. Another advantage of vacuum circuit breakers, which are environmentally friendly as they do not contain any oil or gas, is that they do not carry any risk of explosion. If the vacuum tube is broken in any way, the parts that will form are directed towards itself, not outward, due to the vacuum, and do not pose a risk to the operating personnel. Vacuum Circuit Breaker performs the opening and closing operations by using the energy stored by the opening and closing springs. Installation of the closing spring is possible manually or by means of a motor. The mechanism used in vacuum circuit breakers is "trip-free" (opening is priority. The mechanism is produced in accordance with the "0-3s-CO-15s-CO" operating cycle in accordance with IEC standards. Vacuum Circuit Breakers are suitable for electricity operators with their high breaking capacity and minimum maintenance feature. Vacuum Circuit Breakers are designed with Side Mechanism in accordance with the modular cell structure, placed inside the "Epoxy Pole" to protect the vacuum tubes against harsh environmental conditions.Vacuum providing high performance during the interruption of short circuit currents as well as carrying and breaking the rated currents. Circuit Breakers minimize operating and investment costs with their high number of reliable switching performance.
