An industrial electrical panel houses the switching, protection, and control equipment for a factory's electrical system. A panel designed and built to the appropriate standards helps production lines operate reliably, ensures user safety, and makes maintenance easier.
01What Is an Industrial Electrical Panel?
An industrial electrical panel is a metal enclosure containing electrical devices such as circuit breakers, contactors, relays, variable frequency drives, programmable logic controllers (PLCs), and HMI displays, together with busbars and wiring.
The panel distributes power, protects equipment against overloads or short circuits, and controls machinery according to programmed instructions.
02Common Types of Industrial Electrical Panels
- Main switchboards (MSB) and sub-distribution boards: distributing power to different areas of the plant.
- PLC – HMI control panels: controlling production lines according to programmed logic and connecting to SCADA systems.
- Power distribution panels: power supply and protection for motors, pumps and fans.
- Power factor correction capacitor cabinets (cos φ): improve power factor and reduce reactive power penalties.
- Variable frequency drive control cabinets: adjust motor speed and save energy.
03Industrial electrical panel installation process
- Survey existing conditions and agree on process and capacity requirements.
- Design circuit diagrams, equipment layouts and cabinet enclosure fabrication drawings.
- Fabricate cabinet enclosures, apply powder coating, install equipment and complete wiring according to the drawings.
- PLC – HMI programming, de-energized checks and workshop testing.
- Factory installation, commissioning, acceptance and handover of technical documentation.
- Warranty, maintenance and technical support during operation.
04Criteria for choosing an electrical panel manufacturer
