<p>A SHAFT ASSEMBLY (103) OF A CIRCUIT BREAKER COMPRISES A LATCHING PLATE (131) ROTATABLY COUPLED TO A MOVEABLE PLATE (121), AND TENSILE TYPE LATCHING SPRINGS (134), EACH LATCHING SPRING (134) HAVING TWO ENDS FIXED TO THE LATCHING PLATE (131) AND THE MOVEABLE PLATE (121), RESPECTIVELY. TIME TAKEN FOR A MOVEABLE CONTACT (121A) TO BE LIFTED UP FROM A CONTACT (121A) TIME POINT BETWEEN THE MOVEABLE CONTACT (5A) AND A FIXED CONTACT MAY BE SHORTENED, AND THUS A TIME DURATION FOR WHICH AN ACCIDENT CURRENT FLOWS MAY BE REDUCED. ACCORDINGLY, THE AMOUNT OF ENERGY APPLIED TO THE CIRCUIT BREAKER MAY BE REDUCED, AND A BREAKING FUNCTION OF THE CIRCUIT BREAKER MAY BE ENHANCED. FURTHERMORE, SINCE A CONTACT PRESSURE BETWEEN THE MOVEABLE CONTACT (121A) AND THE FIXED CONTACT (5A) HAS A CONSTANT CHANGE, A RELIABILITY ON A CONDUCTIVE STATE OF THE MOVEABLE CONTACT (121A) AND THE FIXED CONTACT MAY BE ENHANCED.
