6 The hydraulic fluid regulates the cores speed of travel, thereby creating a controlled time delay which is inversely proportional to the magnitude of the time delay is useful in that if the overload is of short duration, start up of motors, etc, the core returns to its rest position once the overload the overload persists, the core reaches the pole piece after a time delay particular to that current and in so doing, the reluctance of the magnetic CIRCUIT drops considerably, so that the armature is attracted to the pole face with sufficient force to collapse the latch mechanism (toggle) and consequently trip the contacts separate, the current ceases to flow, and the core returns to its rest high values of overloads or short CIRCUIT , the magnetic flux produced by the coil is sufficient to attract the armature to the pole face and trip the breaker even though the core has not moved.

7 This is called the instantaneous trip region of the CIRCUIT breaker thermal CIRCUIT BREAKERS , the hydraulic magnetic CIRCUIT breaker s trip point is unaffected by ambient temperature. After tripping, the breaker may be re-closed immediately since there is no cooling down time the nature of the principle of operation, it is possible to obtain any variation of time / current !!!!!
