Can the AC contactor cut off the short circuit current?
contact system, including three main contacts and one to two groups of normally open, normally closed auxiliary contact, it is moving together with the core is linked to each other
electromagnetic system, including the attracting coil, moving core and static core;
Because the AC contactor is only a switch-type device, no current detection and feedback device, so in practice, often with the appropriate thermal relay or electronic protection device into an electromagnetic starter, in order to protect the circuit may occur overload or phase failure.
A separate AC contactor is not actively shut off the short circuit current.
