In such applications the lifetimeof the equipment is normally limited by the short lifetime of the electromechanical contactor. Electromechanical contactors are not designed to switchoff motors in locked rotor- or overload conditions where the current is 6times the nominal operational current (AC-4). The servere arcing will burnthe contact elements resulting in unreliable contact function.The Semiconductor Contactor will close the contacts in the zero crossing of the mainsvoltage and switch-Off will always occur in the zero crossing of the motorcurrent in this way voltage kickback from the inductive motor windings isavoided. The lifetime, therefore, of the Semiconductoc Contactor will alwaysbe at least one decade longer than the electromechanical contactor.Comparison of lifetime in different utilization actorAC-52aControl of slip-ringmotors, starting,switching Off0.7 Mill.
