Motor control and protection

Benefits and advantages

UMC100.3 is a flexible, modular and expandable motor management system for constant-speed low-voltage range motors.
It's most important tasks include motor protection, prevention of plant standstills and the reduction of down time. This is made
possible by early information relating to possible motor problems which avoids unplanned plant standstills. Even if a motor
trips, quick diagnosis of the cause of the fault serves to reduce downtime.
UMC100.3 combines in a very compact unit:

Motor protection Communication
– Overload, underload – Communication-independent basic device
– Overvoltage, undervoltage – Freely selectable fieldbus protocol with FieldBusPlug
– Blocked rotor, low / high current – Profibus DP
– Phase failure, imbalance, phase sequence – DeviceNet
– Earth leakage – Modbus RTU
– Thermistor protection – Ethernet Modbus TCP
– Limitation of starts per time – Profinet
– One single version with integrated measuring system cov- Typical application segments
ers the rated motor current from 0.24 to 63 A – Oil & gas
