Heater element failure, loss of load, peak power loads, and load jams are just a few examples of faults motors may be subjected to. Littelfuse SymCom single and three-phase current monitors provide protection against these load side faults and others when the motor is running. SymCom three-phase monitors protect against single-phasing and current unbalance problems that can be caused by voltage supply problems, bad contactors, or loose wiring. They also provide very reliable overload and underload protection.
