  • the speed of separation between the contacts is one of the main parameters to guarantee the break and the dielectric strength of the circuit breaker when it is opened.
  • contact means the whole of a permanent contact, also called principal, constituting an electrical contact (possibly with its hood). discharge guard) through which the nominal permanent current passes and an arc contact on which an electric arc is established during a power failure.
  • Cutoff chambers that include a movable contact and a fixed contact are commonly referred to as "single-motion”.
  • cutoff chambers which comprise two opposite contacts and which are simultaneously movable one and the other are commonly called "double movement".
