机械，电气寿命：10,000使通断满负荷周期，每个电路。
MECHANICAL and ELECTRICAL LIFE: 10,000 make-and-break cycles at full load, each circuit.
合金的接触电阻相对较小，电气寿命升高，具有良好的电接触性能。
The contact resistance is relatively smaller and electrical life increases, it has good electrical contact performances.
通过对接触器通断过程的智能操作，可以减少触头的电弧侵蚀，并提高接触器的电气寿命。
By the use of intelligent operation in make and break process of ac contactors, the contacts erosion will be reduced, which lengthens causes the electrical durability of the contactor.
