GE CK09BE311N CK Series Magnetic Contactor

Feature & Principle

After the coil is energized, the electromagnetic force pulls the moving contact to close, turning on the main power loop for motor startup operation. When power is lost, the return spring separates the contacts to cut off the circuit. Built-in auxiliary contacts provide status feedback for PLC interlock control, with arc extinguishing structure to suppress electric arc during breaking.
