What Causes A Contactor Coil To Burn Out. learn how to identify a bad contactor coil in your electrical systems. The coil is burned out by excitation rush current (10~15 times of holding current) flowing into the coil, if you operate it continuously without perfect inhalation after the power voltage decreases abnormal material penetrates the magnetic contact pole. ensure the operating voltage of the application and the rated voltage of the contactor’s coil are compatible. Contactor overheating, which results in severe pitting or deformation of the contact surface, can occur if too much current is transmitted, if the contactor does not close quickly and firmly enough, or if it opens too frequently. The common contactor coil failures are: there are a number of common reasons for contactor failure. In this condition, enormous current flows through the contacts, and if the protection devices do not trip the circuit in a timely manner, the huge current may cause contact sticking or contact welding. We’ll learn how to recognize unusual noises that may indicate electrical contactor problems, and how to handle overheating concerns caused by overloads or faulty connections. by far the most common cause of contactor coil failure is undervoltage. A short circuit occurs when the phase wire touched to neutral wire. beginning with a complete visual inspection, we’ll go into identifying damage in electrical contactors like burning, corrosion, or loose connections. There may be sufficient voltage to pull the contactor in, but not enough to keep the coil armature. what causes a contactor coil failure?
