Functions in detail

UMC100.3

Motor protection Motor control
• The UMC provides comprehensive • Integration of the most important motor
motor protection control functions as ready, easily
• Overload protection for single- and three-phase parameterizable blocks
AC motors according to EN/IEC 60947-4-1 • Direct, reversing, star-delta starters
• Rated motor currents from 0.24 to 63 A with • Pole changing Dahlander / Actuator mode
integrated measuring system in a single version • Inching / jog mode
• Rated motor currents up to 850 A with external • Adjustable restart strategy (load shedding)
current transformer CT4L / CT5L
• Selectable tripping classes 5E, 10E, 20E, Extended motor control
30E or 40E • Freely programmable for special,
• Locked rotor protection application-specific control functions
12
• Phase failure, asymmetry and sequence • Simple adaptation to specified
protection control functions
• Under-/overcurrent protection • Comprehensive library
• Thermistor motor protection • Blocks for logic, counters, timing
• Ground leakage detection – internally • Access to all I/Os and internal signals
or using CEM11 sensor

• Motor protection independent from
bus communication

In combination with voltage module VI150/
VI155-FBP.0
• Undervoltage/overvoltage protection
• Power supervision
• Power factor supervision (cos j)
• Voltage-based detection of phase failure,
asymmetry and sequence
