2021/5/25The flow pattern can be controlled by splitting the fixed arcing contact (arc pin) and giving the fixed main contact multiple contact members with pressure release openings. Further, the gas outlets should be large enough to avoid the flow of hot gas toward the main contact and any change in the contacts should not sacrifice the required cross section of the main current path →07 .
