ABB’s CM range offers a wide selection of powerful, compact devices for the monitoring of currents and voltages in single-phase AC/DC systems. All come in a housing that is just 22.5 mm wide. This product 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. ABB’s CM range gives your electric installation the highest safety and reliability...
The reliable and continuous monitoring of three-phase networks guarantees the trouble-free and cost-effective operation of machines and installations. ABB’s CM-MPS/N three-phase monitoring relays for rated voltage levels up to 820 V AC and 400 Hz offer maximum flexibility and control...
ABB’s CM-UFD range are multi-functional grid feeding monitoring relays, installed between the renewable energy system and the public grid. They detect unusual events in the public power grid and automatically disconnect and reconnect the renewable power plant. Different monitoring functions such as 10-minutes average value, real time over- and undervoltage as well as over- and underfrequency are configurable via the front face display. Versions with a Modbus RTU...
ABB’s CM-IWx insulation monitoring relays for IT systems provide continuous, reliable monitoring. The devices recognize insulation faults as they develop, tripping as soon as the value falls below minimum set thresholds. This makes systems more reliable and prevents interruptions caused by severe secondary insulation faults. Make your monitoring more secure and your maintenance smarter with CM-IWx insulation monitoring relays...
ABB’s CM-MSx.xx range of thermistor motor protection relays monitor the winding temperature of motors. PTC sensors integrated in the motor windings directly measure the motor heat. This direct temperature measurement enables the thermistor motor protection relays to evaluate various motor conditions such as overheating, overload and insufficient cooling. ATEX approval is also available for products used in hazardous areas...
ABB’s CM-TCS relay range monitors and measures the temperatures of solids, liquids and gaseous media using a variety of different sensors. Overtemperature and undertemperature monitoring as well as open- or closed-circuit principle monitoring can be configured for any device quickly and easily...
ABB's liquid level monitoring relays are used for regulation and control of liquid levels and mixture ratios for conductive fluids. The range includes single function and multifunctional devices that can be used for overflow, dry-running protection of pumps, filling and draining applications as well as maximum and minimum level alarms. A wide selection of accessories complete the offer...
