An electrical panel is a system that contains many electrical circuits and components and is used for the distribution, control and protection of electrical energy. It is usually housed in a metal box or cabinet and may contain many electrical components. Electrical panels are used in industrial facilities, building electrical installations, energy distribution systems and various other applications.
The electrical panel may include many important components:
Main Breakers and Main Switches: These are the main breaker or main switches that connect the main power supply to the panel. These components control the entry of electricity into the panel and disconnect the facility from electricity in case of emergency.
Circuit Breakers (Fuses or MCCBs): Circuit breakers that provide protection in cases of overcurrent or short circuits in electrical circuits. These provide protection against overload and ensure the safety of the system by interrupting the electrical current.
Contactors and Relays: The electrical panel contains contactors and relays used to perform control operations. These components perform the functions of turning circuits on and off, controlling motors, and performing other electrical functions.
Measuring Devices: Measuring devices used in the electrical panel are used to measure electric current, voltage, power factor and other electrical parameters. This information can be used to monitor and evaluate system performance.
Distribution Panels and Switchgear: The electrical panel may include distribution panels used to distribute energy between different circuits. Additionally, switchgear may include components such as switches, push buttons, and indicators used to control different devices or equipment.
Cable Connections and Terminals: The electrical panel contains terminals and junction boxes for connecting cables. These components ensure a safe and tidy cable connection.
Electrical panels provide safe and effective distribution, control and protection of electrical energy. These reduce the complexity of electrical systems, reduce operating and maintenance costs and increase plant safety.
