IEC Motor Control & Protection

Innovative Systems for Flexible Solutions

The market-leading Modular Control System (MCS) offers you more freedom to configure load feeder solutions through 1200 A. MCS load feeder components provide the following control and protection functions:

  • Disconnecting means
  • Short-circuit protection
  • Load switching
  • Motor overload protection
  • Status indication and signaling
  • DeviceNet™ communications
