Product Description
ABB MCU2A02V2-4, Order Code 1SCA022657R9090, is an INSUM MCU2 intelligent motor control unit, the core module for low voltage motor management system, now discontinued. This unit integrates motor measurement, protection, control and fieldbus communication. It directly measures main circuit voltage 380–690V AC, with measuring current range 2.0~63A. It uses 24VDC auxiliary power supply, spring clamp terminals and DIN rail mounting. It is installed inside low-voltage switchgear for intelligent management of motor circuits. It provides full motor protection, start/stop control, operating data acquisition and fault diagnosis. It connects to INSUM system via VLA bus for remote motor circuit monitoring.

Application
- Comprehensive protection and intelligent control for 3-phase asynchronous motor circuits in low voltage switchgear and MCC motor control centers.
- Motor loads such as pumps, fans and conveyors for water treatment, HVAC, petrochemical, power plant and manufacturing industries.
- INSUM motor management system for remote motor monitoring, parameter setting, fault alarm and event logging.
- Real-time measurement of motor current, voltage and operating status; protection against overload, locked rotor, phase loss, phase unbalance, under-voltage and over-voltage.
- Used with withdrawable / fixed type low voltage switchgear, replacing conventional thermal relays to upgrade intelligence of motor feeder circuits.
