(DPU module of Kongsberg, can be common used for several motor starters)

Option 2: Intelligent motor starter

Except 2 necessary components: circuit breaker (or fuse switch) and contactor(s), there is only another component so called Motor Control Unit (MCU) which is essential to make up of an intelligent motor starter. The MCU is a microprocessor based intelligent module which provides full motor control, protection and monitoring functions. It can transmit real-time data upward to control centre and receive operating command in reverse via communicating with up-level Automation System.

Depending on individual functions, typically a basic motor starter consists of, but not limited to following components:

1 pc MCCB 3P with instantaneous tip, or Fuse Switch 1 pc MCU with correlating operating panel 1 unit Magnetic contactor(s) 1 pc Operation mode switch (Auto/Hand or Local/Remote, where applicable) 1 pc “Heating” indicating light (blue, where applicable) 1 pc “Heater on” switch (where applicable) 1 lot Fuses for control circuit 1 pc Control transformer (can be common used for several motor starters) 1 pc Common used 24VDC power supply unit (for all motor starters in the MCC)
