What is the difference between power contactors and ampauxiliary contactors?

Power contactors are electromechanical devices used to switch electrical circuits on and off, typically handling high current loads in industrial applications. They are designed for high voltage and current operations, providing control over large motors and equipment. In contrast, auxiliary contactors are smaller devices used to provide additional contacts for control and signaling purposes, often used alongside power contactors to enhance functionality. While power contactors manage the main power flow, auxiliary contactors support control circuits, enabling functionalities like indication, interlocking, or automation.
