Main Distribution Board (MDB) panels provide the primary distribution point for power in industrial, commercial, and utility installations, feeding sub-distribution boards (SDBs), loads, and critical systems.
What Are MDB Panels?
MDB panels are the central distribution point that:
• Receives power from the incoming source (generator, transformer, or utility)
• Distributes power to multiple circuits via busbars and outgoing feeders
• Integrates protection devices (ACBs, MCCBs, RCCBs) for safety and control
• Provides monitoring and control interfaces for operators
Key Features
• High current capacity – Designed for main incoming currents from 400 A up to 4,000 A or more
• Robust construction – Steel or aluminum enclosures with high mechanical strength
• Protection & safety – Integrated protection against short-circuit, overload, and earth fault
• Flexibility – Configurable for single or dual incoming sources, with options for tie feeders and bus couplers
Applications
• Industrial Plants – Main power distribution for production areas and utilities
• Commercial Buildings – Central distribution for lighting, HVAC, and power loads
• Utilities & Substations – Auxiliary power distribution for control and instrumentation
• Data Centers & Infrastructure – Reliable power distribution for critical IT and facility systems
