Power Control Center (PCC) &
Main LT Distribution Panels
Engineered as the primary electrical backbone for heavy manufacturing plants, automotive corridors, and commercial high-rises. Adhunik Powertech builds custom substation intake boards with motorized source synchronization, Form 4b internal segregation, and verified 65kA short-circuit fault withstand capacity.
Engineered for Maximum Continuity & Complete Operator Safety
Adhunik Powertech PCC boards combine heavy-gauge fabrication with smart protective relaying.
Intelligent ACB Incomers
Drawout Air Circuit Breakers up to 4000A with microprocessor-based LSIG (Overload, Short-Circuit, Instantaneous, Earth Fault) trip units, offering zone-selective interlocking (ZSI) and motorized remote operation.
Form 4b Isolation Alleys
Total separation between busbars, functional breaker compartments, and external cable connection alleys ensures that technicians can service isolated feeder modules without de-energizing the main power line.
Auto-Source Synchronization
Dual incomer changeover schemes (Transformer + Captive Generator) with programmable bus-coupler logic, auto-mains-failure (AMF) controllers, and reverse power protection for seamless changeover.

Rigorous 4-Stage Factory Acceptance Testing (FAT)
We invite clients, consultants, and inspection agencies to witness full validation prior to dispatch.
Megger Test (1000V DC)
Phase-to-phase and phase-to-earth insulation resistances tested above certified threshold limits.
High-Voltage (2.5 kV)
Auxiliary and main busbar power circuits subjected to 2500V AC for 60 seconds without leakage.
Busbar Torque Verification
Joint conductivity confirmed with calibrated torque wrenches and high-current millivolt drop inspection.
Functional Interlock Checks
Live simulation of ACB auto-trip cycles, bus-coupler interlocks, and Modbus meter register polling.
