ABSTRACT:
A circuit breaker actuating device comprising valve means interposed between a high pressure section of an operation fluid and a low pressure section thereof to preclude communication therebetween and adapted to cause a variation in pressure to occur either in a high pressure source or low pressure source when actuated to establish communication between the high pressure section and the low pressure section, so as to thereby actuate piston means and cause a circuit breaker to perform a current interrupting operation.
