Vacuum Circuit Breakers - Fuji Electric
www.fujielectric.comoperating mechanism has been designed to reduce the size and mass of the circuit breakers. Spring closing system The vacuum circuit breakers use a motor-spring stored-energy mechanism (rapid auto-reclosing type) to provide stabilized electrical and mechanical characteristics and to reduce the closing operating current.

www.gegridsolutions.comMechanical movement of the operating mechanism is imparted to a contact structure to close or to open contacts. When we say that a relay "operates," we mean that it either closes or opens its contacts-whichever is the required action under the circumstances. Most relays have a "control spring," or are restrained by gravity, so that they assume ...

library.e.abb.comThe operating mechanism is fundamentally suitable for auto-reclosing and, due to the short charging times, also for multi-shot auto-reclosing. The generator breaker have a built-in mechanical delay system with which the opening time is prolonged by approx. 30 ms. In the basic version of the circuit-breaker, the spring energy store is charged ...
