THE COMMON USE OF ELECTRICAL DEVICES
THE COMMON USE OF ELECTRICAL DEVICES
An industrial electrical system requires a combination of many specialized devices to ensure safe, stable, and efficient operation. Below is a summary table of the 25 most common industrial electrical devices along with the main function of each type:
Switching and Protection Devices
1. MCB (Miniature Circuit Breaker): Protects against overload and short circuits.
2. RCCB (Residual Current Circuit Breaker): Provides protection against current leakage and electric shock.
3. Isolator: Isolates the power supply for maintenance and repair work.
4. ATS (Automatic Transfer Switch): Switches between two power sources (Grid/Generator).
5. SPD (Surge Protective Device): Protects equipment from transmitted lightning surges and overvoltage.
Control and Display Devices
6. Multifunction Power Meter: Measures voltage (V), current (A), frequency (Hz), power, energy, etc.
7. Push Button: Used to control circuits: start, stop, reset, etc.
8. Indicator Lamp: Indicates status: powered, fault, running, etc.
9. Selector Switch: Selects operation modes: Auto/Manual, A-M, etc.
10. Emergency Stop Button: Emergency stops machinery in dangerous situations.
Power Switching and Automatic Control Devices
11. Contactor: Switches power for motors and heavy-load applications.
12. Thermal Relay: Protects motors from overloads.
13. Timer Relay: Creates delayed closing or opening according to set time.
14. Industrial Plug (16A): Industrial plug, high load capacity, used for 3-phase power supplies.
15. Industrial Socket (16A): Industrial socket, high load capacity, used for 3-phase power supplies.
Wiring and Panel Accessories
16. Cable Gland: Secures and seals cables entering the electrical panel, resisting dust and water.
17. Wiring Duct: Manages, organizes, and protects wiring inside the electrical panel.
18. Terminal Block: Provides safe and secure wire connections between electrical circuits.
19. Copper Lug: Connects cables to equipment and busbars.
20. Ferrules: Enhances mechanical durability and ensures crimping quality.
21. DIN Rail: Standard mounting rail for installing devices inside electrical panels.
22. Cooling Fan: Provides cooling and ventilation for electrical panels and equipment.
23. Panel Box: Protective enclosure for installing and housing electrical equipment.
24. Cable Tray: Supports and routes electrical cables throughout the system.
25. Conduit Pipe: Protects electrical cables from mechanical and environmental impacts.
