Product Overview
The ABB UMC100.3 is an intelligent motor-management system combining motor protection, control, monitoring, communication and fault diagnosis in one compact unit.
It is commonly installed in low-voltage Motor Control Centres to protect pumps, fans, compressors, conveyors and other constant-speed motors. The controller continues protecting the motor even if communication with the PLC or control system is interrupted.
