The vacuum circuit breaker has become the technology of choice for high voltage applications from the day it was born, with a challenge from SF 6 gas in the 1980's and 1990's. 5 kA/2500 A. High Sky RV Parts is not responsible for your warranty. Note Danger of tipping over due to shift in centre of gravity! Vacuum circuit-breakers with mounted contact arms may tip onto the contact system if not fixed. When contacts of a breaker are opened in vacuum, the interruption occurs at first current zero with dielectric strength between the contacts building up at a rate thousands of times that obtained with other circuit breakers.
