SymCom current monitors have many advantages over voltage monitors because they provide protection against both supply line and load side faults when the motor is running. They protect against single-phasing and current unbalance problems that can be caused by voltage supply problems, bad contactors, loose wiring, bad wires or damaged motors. SSAC current monitors also provide very reliable overload and underload protection. Littelfuse current monitors are used to detect heater element failure, loss of load, peak power loads, runway and radio tower light failure, feed rate, dull bits and blades, conveyor load jams, current demand level and to keep tooling loads at their most efficient point. Heater element failure, loss of load, peak power loads, and load jams are just a few examples of faults motors may be subjected to. 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.
