MCC switchgear

An MCC switchgear (Motor Control Center) is a central control and distribution unit for electrical drives in industrial plants and power distribution systems. It consists of several switch panels containing motor starters, protective devices, circuit breakers and control units.

MCC switchgear is often used in power transmission, power distribution, automation technology and industrial manufacturing to ensure safe and efficient control of electrical systems.

MCC switchgear consists of several switching units housed in an MCC control cabinet. Each unit contains circuit breakers, contactors, motor protection relays and control components that ensure safe and efficient operation of the motors.

The main component of a Motor Control Center is the power supply, which is provided via a main busbar line. From there, the electrical energy is distributed to the individual motor outputs. Each motor is controlled via a separate MCC switching unit, which provides short-circuit, overload and phase failure protection. Modern variants are equipped with circuit-breakers with thermal-magnetic tripping or electronic protection systems that enable precise monitoring.

Automated motor switching systems are equipped with frequency inverters, soft starters or direct starters, depending on the requirements of the application. The systems can be integrated into higher-level control systems via communication interfaces such as Modbus, Profibus or Ethernet. This enables remote monitoring, fault diagnosis and energy optimization in real time.

ATCE ENERJ develops robust and scalable MCC switchgear that ensures operation and minimizes maintenance costs. With precise control technology and integrated protection mechanisms, our systems ensure maximum operational reliability and energy efficiency in industrial applications.

MCC switchgear is particularly important for the safe operation of electrical drives. In an MCC control cabinet, protective relays are used to monitor current, voltage and temperature. Thermal protection relays react to overheating caused by increasing motor current. Electronic protective relays precisely detect overload situations, phase failures and earth faults.

Our Motor Control Centers use digital protection systems with programmable parameters. These relays continuously measure the operating status and switch off motors in a targeted manner before critical damage occurs. Motor protection relays with direct communication via Modbus or Profibus are often used in an MCC switching unit.

ATCE ENERJI integrates high-quality protective relays into motor switching systems in order to detect short circuits, load peaks and asymmetrical mains voltages at an early stage. Our MCC switchgear ensures reliable motor control and minimizes downtimes through preventive shutdowns.

MCC switchgear is subject to strict technical specifications in order to ensure safe and efficient motor control. The IEC 61439 and IEC 60204 standards are particularly relevant for motor control centers and other switchgear for motors. ATCE ENERJi develops and manufactures motor control centers that meet the highest electrical and mechanical requirements.

IEC 61439 defines the design, test methods and short-circuit resistance of MCC switchgear. It ensures that all components can withstand the thermal and electrical loads. IEC 60204 specifies which protective and control elements may be used in machine control systems for MCC switchgear. The Low Voltage Directive 2014/35/EU and EMC directives for electromagnetic compatibility are also relevant.

ATCE ENERJi integrates high-quality circuit breakers, protective relays and control systems to maximize operational safety and energy efficiency. Our MCC switchgear minimizes switching losses, optimizes load flows and ensures trouble-free power distribution in complex industrial applications.

ATCE ENERJI MCC switchgear is designed for efficient motor control and power distribution. They can be adapted precisely to the individual tasks for motors. The configuration is based on power requirements, control requirements and safety specifications.

Our MCC switchgear has a modular design and enables flexible integration into existing systems. Circuit-breakers, protective relays and control units are individually dimensioned to reliably control overloads, short-circuit currents and mains fluctuations. Intelligent control modules with PLC or frequency converter technology ensure precise control of the connected drives.

The housing design can also be adapted to the ambient conditions. Dust or moisture-proof designs ensure operation in demanding industrial environments. We also supply MCC switchgear for redundant power supply and remote monitoring.

ATCE ENERJ designs MCC switchgear that combines efficiency, safety and durability. Individual planning and high-quality components result in robust switching systems for reliable energy and drive technology.
