Motor Control Center (MCC) & Power Control Center (PCC)

Motor Control Center

A Motor Control Center (MCC) is an assembly that controls several or all-electric motors centrally. There are multiple enclosed sections and a common power bus. Each section has a combination starter, which consists of a motor starter, fuses or circuit breakers, and a power disconnect. It is also possible to equip a motor control center with push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. In some buildings, it may be combined with the electrical service entrance.

Typically, Motor Control Centers can be found in large industrial or commercial buildings containing a lot of electrical motors that must be controlled centrally, such as an electrical room or mechanical room.

Power Control Centre

A Power Control Centre (PCC) is a main power control panel that contains feeder breakers and supply breakers, monitoring devices, control devices, switching devices, protection devices, and instrumentation devices. Alternatively, it is called the Main Switchboard. This type of switch is mainly installed near power sources, so its fault level is high. In order to function properly, it must be able to satisfy 50KA or 65KA fault levels for 1 second.

A Power Control Center’s bus bar system is designed to handle fault levels and temperature rises up to 40 degrees Celsius. The termination of cables is provided with ample space. In order to protect the source and equipment, various protections are provided, such as short circuits, overloads, earth faults, under voltages, etc.


How does the Motor control Center & Power Control Center Panel Operate?

  • Many industrial processes require a large number of motors, so Motor Control Centre (MCC) panels are used to regulate them all. With the Motor control Center, the control components can be plugged in or unplugged, eliminating the need for wiring. A motor control center would consist of a bus bar and other control equipment to control the motor’s operation and integrate the components into a panel. Motor control Center supports several motor starting methods, including DOL and star-delta starters. A motor control center includes feeders for motors and blowers. Feeders are designed based on motor power ratings. The majority of Motor control Centers will have auto/manual options. It is possible to operate motors manually with manual provision.
  • A Power Control Center panel monitors and controls the voltage and power of a power system. In addition to being made of high-quality raw material, these panels are extremely sturdy in construction. The main power instrument panel consists of feeder breakers, provide breakers, monitoring devices, and control devices. A reputable Power Control Center panel manufacturer reads all field data received for electrical power panels. Power Control Center panels and LT panels are made of 14/16 SWG CRCA material, semibold, and firmly supported. It ensures the desired breaking capacity, temperature rise, and IP protection. Ample space for terminating incoming and outgoing cables. According to IEC standards, outgoing terminals are of the stud type.

Advantages of Motor control Center

Using Motor control Centers, components can be coordinated from a single point. If compared to separately mounted controls, pre assembled and pretested electrical distribution and motor control equipment is generally less expensive to install.

  • The Motor control Center requires significantly less line-side power wiring than separate controls, making them easier to install.
  • An Motor control Center’s packaging is space-efficient, and it offers excellent configuration flexibility. Maintenance is also centrally managed.
  • Electrical component isolation and fault containment are excellent features of Motor control Centers.

Motor control Centers are used when multiple, remotely controlled loads are linked to a central control point. An industrial plant’s central control point is usually its environmental control system, which controls HVAC, pumps, and fans. Industrial process equipment includes a wide variety of load types, such as conveyors, pumps, fans, and mixers. These loads are often controlled in a coordinated manner and can provide important diagnostic information about a machine or process. This type of control and data acquisition functionality is typically provided by a distributed control system (DCS) or a programmable logic controller (PLC).


Advantages of Power Control Centre

  • This Power Control Centre is compact, safe, and reliable.
  • Users will find the Power Control Centre to be user-friendly.
  • Power Control Center with single and multiple incomers, bus couplers, with proper interlocking on the main LT panel.
  • The system provides the required protection, fault indications, and interlocking.
  • The Power Control Center is offered in a variety of designs, such as top, middle, and bottom horizontal bus chambers, panels with aluminum/copper bus bars, top/bottom/front/rear cable terminations, and combinations with APFC Parts.
  • Provide facilities such as DGIncomer with AMF functions and cut off non-essential feeders in the event of a power failure.
  • On the main incomer side, a panel is provided with a provision for connecting the bus duct.

Difference between Motor control Center and Power Control Center Panel

MCC stands for motor control center panels, while PCC stands for power control center panels. Generally, Motor control Center refers to a panel that supplies LT motor power, while Power Control Center refers to a panel that receives HT power. However, there is a difference between them in terms of protection relays and type of insulation.

In other words, many industrial and commercial applications call for a large number of electric motors. Therefore, there is a tendency to want to manage some or all of them from one place. In this case, the motor control center (MCC) is used. While on the other hand, a Power Control Centre is used to distribute and control various power sources used in industry.
