Symptoms We Resolve
COMMON STAR-DELTA STARTER FAULTS
STAR CONTACTOR FAILURE
A failed star contactor can prevent the motor accelerating correctly during the initial start period.DELTA CONTACTOR FAILURE
If the delta contactor does not engage, the motor may fail to transition to normal running operation.TIMER FAULTS
Incorrect or failed transition timing can cause nuisance trips, poor acceleration, or heavy current during changeover.ELECTRICAL INTERLOCK FAULTS
Auxiliary contacts prevent star and delta contactors closing simultaneously. Failed interlocks can stop the starter entirely.MOTOR OVERLOAD TRIPS
Electrical or mechanical loading can cause the overload to operate during or after starting.BURNT CONTACTS OR TERMINALS
Repeated high-current starting can create heat and deterioration at contactors and terminations.
