Schneider Electric Power Control Center (PCC)

The Schneider Electric Power Control Center (PCC) product entry describes an IEC 61439-compliant, factory-engineered PCC built around Schneider’s switchgear and controlgear ecosystem — Prisma Set type‑tested switchboards, Masterpact MTZ air circuit‑breakers, Compact NSX/Molded Case Circuit Breakers, TeSys motor controllers, Linergy flexible busbars and PowerLogic/EcoStruxure monitoring. PCC assemblies are designed for transformer/main distribution duties (rated voltage up to 690 V AC) with system rated currents engineered up to 6300 A using Masterpact frames, and type‑tested Prisma Set modules for unit ratings up to 4000 A where applicable. Short‑circuit withstand and making capacities are typically specified in the 65–120 kA (1 s) range, and thermal, dielectric and short‑circuit verification testing is executed in accordance with IEC 61439‑1/2 requirements and IEC 60947 series for switchgear components. Internal segregation follows IEC 61439 forms of separation: Form 3b through Form 4b implementations are available to provide separation between incoming feeders, busbar, functional units and low‑voltage compartments. Typical IP envelopes for PCC lineups range IP31–IP54 for indoor installations (Prisma Set enclosures can be supplied up to IP55 when required), with optional climate and dust control for harsher ambient conditions. Protection coordination and selectivity are achieved using Masterpact MTZ for upstream protection (high breaking capacity and adjustable protection curves per IEC 60947‑2), Compact NSX or NS breakers for distribution feeders, and TeSys contactors/soft starters for motor control. Linergy busbar systems provide low-impedance, compact distribution with proven short‑circuit energy absorption and phase segregation to maintain rating continuity under fault clearing. Power monitoring and energy management are integrated using PowerLogic meters (PM8000/PM5000 families) and EcoStruxure connectivity for local SCADA/BMS or cloud analytics; typical features include demand management, harmonic analysis and logging to support power quality compliance and IEC 61000 compatibility assessments. PCCs built with Schneider families are suitable for data centers, heavy industry, mining, oil & gas terminals, campuses and utility‑connected substations where a combination of type‑tested switchboard modules and high‑current breaker frames are required. Design validation adheres to IEC 61439 verification (routine and type tests), coordination studies per IEC 60947, and, where applicable, hazardous area standards IEC 60079 for explosion‑protected installations.
