Overload is a common cause of motor starter failure, often referred to as an overload trip. Overload protection is a safety mechanism that causes the circuit breaker to trip when the total current exceeds the breaker’s capacity. As explained in the new guide, there are several reasons why trips happen, from worn bearings to loose electrical connections.
The guide provides tips for identifying and resetting an overload trip once the root cause has been found. Electrical Power and Control (EPC) stresses the importance of de-energizing circuits before carrying out overload repairs to ensure safety.
When investigating the overload relay, visible signs of damage, such as burned or melted coil, may be identified. This points to an overload failure, explains the guide, and will require replacement instead of repair.
Alongside overload issues, motor starter failure can also be caused by power supply issues. “Some motor starters require a three-phase power supply to operate,” says Electrical Power and Control, “so if one or more phases are missing, the motor starter won’t function.” The guide advises readers to contact a qualified electrician, who can accurately diagnose the source of the missing phase before corrective action is taken.
Another common power supply issue affecting motor starter functionality is a blown fuse, causing complete or intermittent failure of the motor. The guide suggests using a multimeter tester, in addition to visual inspection, to identify a blown fuse.
“If the fuse is blown, replace it only with an identical fuse with the same amperage rating,” warns EPC. “Never attempt to “fix” a blown fuse by bypassing it or using makeshift alternatives. This can be extremely dangerous and lead to serious electrical hazards.”
Individuals looking for further help diagnosing and repairing a faulty motor starter can contact EPC at (205) 812-5402.
