It works by electromagnetic attraction. After the coil is energized, the iron core pulls the main contact closed to switch on the main power circuit. When power off, the spring resets and disconnects the load. It can be matched with thermal overload relay for motor overload protection, receives control signals from PLC or relay to realize remote on-off control of high-power loads.
