Three-Phase Current MonitorsCurrent Monitors have many advantages over voltage monitors because they provide protection against both supply line and load sidefaults when the motor is running.They protect against single-phasing and current unbalance problems that can be caused by voltagesupply problems, bad contactors, loose wiring, bad wires or damaged motors.They also provide very reliable overload and underload protection.Current monitors are used to detect heater element failure, loss of load, peak power loads, runway and radio tower light failure, feedrate, dull bits and blades, conveyor load jams, current demand level and to keep tooling loads at their most efficient point.<strong>SymCom</strong> current monitors allow installation flexibility by providing models that accommodate built-in or external current transformers.<strong>Model</strong>s 520 and CP-5 require external CTs.Features• Diagnostic Display• Trip Delay• Rapid-cycle Timer, Power-up Timer• Dry-well Timer• Overcurrent Timer• Motor Acceleration• Remote Manual ResetProtects 3-Phase motors from:• Overcurrent• Undercurrent• Current unbalance• Rapid cycling• Single-phasing• Phase reversalProduct Selection MatrixMODEL520CS-115520CS-115-5520CS-230520CS-460520CP-115520CP-115-5520CP-230520CP-230-5520CP-460Phase LossPhase ReversalContact Failure DetectionUndercurrentOvercurrentCurrent UnbalanceRapid CyclingDiagnostic DisplayTrip DelayRD1 Rapid-Cycle Timer, Power-Up TimerRD2 Underload, Dry-Well TimerRD3 Overcurrent Timer#RF Number of Restarts After All Faults#RU Number of Restarts After an UC FaultMotor AccelerationRemote Manual ResetDPDT Relay32 www.symcom.com • tel: 605-348-5580 800-843-8848 • fax: 605-348-5685
