2CDC 255 057 F0008Three-phase monitoring relays CM rangeThree-phase monitoringNEWGENERATION2008.10.012The new generation of three-phase mainsToday, three-phase mains are generally used Approvals / Marks(depending on devices)A UL 508, CAN/CSA C22.2 No.14; C Germanischer Lloyd; D GOST; K CB scheme; E CCC; L RMRS / a; b C-Tick because they allow the most economic transport of high currents as well as simply designed, robust and effi ciently working electric motors.For the monitoring of three-phase mains, ABB’s three-phase monitoring relays of the CM range comprise a comprehensive program of capable and economic devices. All devices feature a width of 22.5 or 45 mm. The range includes multifunctional three-phase monitoring relays as well as single-function devices for the monitoring of individual parameters.Multifunctional and single-functional devicesWide range operating voltage enables world-wide operationMonitoring functions 1):Phase failurePhase sequenceAutomatic phase sequence correctionOvervoltageUndervoltagePhase unbalanceNeutralFixed or adjustable thresholds for over- and undervoltageAdjustable threshold for phase unbalancePowered by the measuring circuitMonitoring of mains with and without neutral conductorDevices with 1 n/o contact, 1 or 2 c/o (SPDT) contactsLED(s) for status indicationEnergy saving of more than 80 % through innovative switch mode power supply technology1) dependig on device࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯࡯Features of three-phase monitoring relays 1)32CDC 255 058 F00082CDC 255 059 F00082CDC 251 042 F00082CDC 253 010 F00032CDC 253 065 F0006...0 0,130 20 102864Three-phase monitoring relay s CM rangeThree-phase monitoringNEWGENERATION2008.10.01All new devices are working with a modern TRMS- measuring principle (True...
