Combined PCC with APFC Panels
The MOBY Combined Power Control Center (PCC) with Integrated APFC is a modern space-saving industrial electrical solution. By housing the main LT incomer air circuit breakers, multiple outgoing feeder breaker compartments, and a multi-step automatic capacitor bank within a single unified, factory-coupled cubicle assembly, it reduces substation civil room footprint by up to 40% and completely eliminates costly external power cable interconnections.

Key Engineering & Operational Features
Why electrical consultants, industrial plants, and utility engineers specify MOBY Combined PCC with APFC Panels.
Up to 40% Substation Footprint Reduction
Eliminates the need for a separate APFC room or freestanding capacitor panel, allowing compact electrical room design and major civil construction savings.
Pre-Engineered Internal Bus Coupling
APFC bank is directly bus-coupled to the primary PCC distribution busbars inside the factory, eliminating dozens of meters of expensive heavy-gauge interconnecting copper cables.
Enhanced Personnel Safety (Form 3b/4)
Individual isolated sheet-steel compartments for incomer ACB, outgoing feeders, busbars, and capacitor steps prevent accidental contact with live buses during maintenance.
Immediate Reactive Power Compensation
Direct bus coupling ensures minimal impedance between the inductive main load and the capacitor bank, providing instant power factor correction and voltage stabilization.
Single Factory Tested Assembly
The combined unit is manufactured, busbar-torqued, control-wired, and rigorously tested as a single integrated assembly before dispatch, ensuring flawless site commissioning.
Centralized Digital Metering & SCADA
Front door features centralized multi-function digital power meters, APFC status controllers, breaker trip indicators, and Modbus RTU communication terminals.
