摘要： PROBLEM TO BE SOLVED: To provide an arc extinguishing device capable of extinguishing an arc at the time of interrupting a short-circuit current without needing a complicated contact structure and not requiring a loss, a radiator, a heat sink, or the like at all times. SOLUTION: A pair of arc running electrodes 5, 6 each having in its middle as an intermediate a PTC element 7 with a positive temperature coefficient of resistance are disposed near main contacts of a molded-case circuit breaker. Resistance of the PTC element sharply increases when the element temperature exceeds a fixed resistance transition temperature, and when an arc generated by opening the main contacts moves to the arc running electrodes 5, 6, the PTC elements 7 are heated to increase their resistance sharply, and as a result, arc sustaining conditions collapse to extinguish the arc.

摘要： PROBLEM TO BE SOLVED: To obtain a current limiter that is capable of suppressing the break down of a positive temperature coefficient(PTC) element by preventing the temperature gradient from being generated, even if the PTC element reaches its resistance transition temperature. SOLUTION: A current limiter 10 is provided with a PTC element plate 11, consisting of first and second PTC elements 11a and 11b that are electrically connected in parallel. The second PTC element 11b is constituted by a PTC element that has a lower resistance and lower resistance change temperature than those of the first PTC element 11a at normal temperatures and a larger resistance change rate, after the resistance change. When a short-circuiting current flows in the current limiter 10, it first flows through the second PTC element 11b, but Joule heat is generated at the second PTC element 11b from self heating, and at the same time the first PTC element 11a is preheated due to this heat. When the second PTC element 11b reaches a resistance change temperature and the resistance is increased, though a short-circuiting current is commutated to the first PTC element 11a, it immediately reaches a resistance change temperature for limited flow since it has been preheated.
