Estimating the term…
A low-voltage multipole circuit breaker with high electrodynamic strength comprises a case made of insulating material, subdivided into a front compartment housing an operating mechanism commanding opening and closing of the circuit breaker and a rear compartment separated from the front compartment by an intermediate wall. The rear compartment is itself subdivided into individual compartments by separating partitions, each individual compartment housing one of the poles of the circuit breaker. The operating mechanism is linked to a pole shaft common to all the poles. The pole shaft is located in the rear compartment and supported by bearings passing through the separating partitions.
A low-voltage circuit breaker of high electrodynamic strength with a case made of insulating material, comprising an operating mechanism linked to a pole shaft supported by bearings securedly affixed to the case, a plurality of poles, each pole comprising at least one pair of separable contact parts, one at least of the contact parts of each pair, called the movable contact part, being mechanically linked to the pole shaft, the pole shaft, operating mechanism and movable contact part being able to move between an open position corresponding to separation of the contact parts of each pair and a closed position corresponding to contact between the contact parts of each pair, the case of the circuit breaker comprising a front compartment housing the operating mechanism and a rear compartment separated from the front compartment by an intermediate wall and subdivided into individual compartments by separating partitions, each individual compartment housing one of the poles of the circuit breaker, wherein the rotation axis of the pole shaft is located in the rear compartment.
