Measuring and monitoring relays Single- and three-phase

Current and voltage monitoring relays Monitoring the parameters of single-phase mains Applications of current and voltage monitoring relays in single-phase mains For the monitoring of currents and voltages in single-phase AC/DC systems, ABB’s CM range contains a wide selection of powerful and compact devices all in only 22.5 mm wide. This meauring range includes current and voltage monitoring relays for over- and undercurrent protection, over- and undervoltage protection and phase loss monitoring – from 3 mA to 15 A and from 3 V to 600 V. Incorporating ABB’s long-term experience the CM...

Three-phase monitoring relays Monitoring the parameters in three-phase mains Applications for three-phase monitoring relays in three-phase mains Only reliable and continuous monitoring of three-phase networks guarantees trouble-free and economic operation of machines and installations. Thus, the three-phase monitoring relays of the CM range monitor the phase voltages, phase sequence, phase unbalance and phase loss. Monitoring for over- and undervoltage All electric devices can be damaged when operated continuously at voltages over or under their rated values. An overvoltage could...

Current and voltage monitoring relays for single-phase AC/DC currents Current monitoring relays Voltage monitoring relays Single-phase voltage and current monitoring relays protect sensitive equipment and control systems against undervoltage (brownout) or undercurrent events or overvoltage or overcurrent events. Different units with adjustable or fixed threshold values (trip points) are available. All devices are available with two different terminal versions. You can choose between the proven screw connection technology (double-chamber cage connection terminals) and the completely...

Single- / multifunctional monitoring relays for monitoring of three-phase mains Singlefunctional The reliable and continuous monitoring of three-phase networks guarantees trouble-free and economic operation of machines and installations. The most multifunctional devices in the EPR assortment are the CM-MPS/N monitoring relays for rated voltage levels up to 820 V AC and 400 Hz. Additionally a variety of economic and cost-efficient three-phase monitoring relays are offered in this range with specialized functionality. Most devices are available with two different terminal versions. You can...
