Straight answers on engineering, standards, FAT and export delivery.
What is an MCC panel and how does it differ from a PLC control cabinet?
A Motor Control Center (MCC) panel is a centralized assembly of motor feeders — each bucket houses its own breaker or fused disconnect, contactor or starter, overload protection and local controls for one motor or group of motors. A PLC control cabinet holds the automation controller, I/O, power supplies and network equipment that sequences and monitors the plant. They work together: the PLC sends start/stop and speed set-points to the MCC over PROFINET or hardwired signals.
What standards are SENTRADO MCC panels built to?
SENTRADO MCC panels are designed and manufactured to IEC 61439-1 and IEC 61439-2 for low-voltage switchgear and controlgear assemblies, and the wiring and control circuits follow IEC 60204-1. Builds operate under our ISO 9001 quality system and carry CCC certification where required. Each panel ships with type-test-aligned documentation, test reports and as-built drawings.
Can VFDs, soft starters and DOL feeders be mixed in one MCC?
Yes. A single SENTRADO MCC can combine DOL and reversing feeders, star-delta starters, soft starters and variable-frequency-drive buckets in one or more connected sections, with dedicated VFD compartments, EMC-rated wiring and harmonic/thermal derating applied as required. Each feeder type is selected against the motor list kW, voltage and duty, and spare capacity is agreed during layout approval.
How do you handle FAT for overseas buyers?
Every export panel undergoes full Factory Acceptance Testing at our own panel manufacturing facility near Beijing. Overseas customers may attend FAT in person in China, witness live testing by remote video link, or appoint an independent third-party inspector such as SGS, Bureau Veritas or TÜV. FAT covers insulation resistance, protection tests, interlocks, functional sequences and communication checks, with signed reports issued before shipment.
What is the typical lead time for an export MCC?
For a standard export MCC, the shipment-ready schedule is about 11–14 weeks: engineering and drawing approval takes 3–4 weeks, panel manufacturing 6–8 weeks, and FAT with rectifications 1–2 weeks. The clock starts after order confirmation and approved documentation; spares or shipping arrangement are quoted separately.
What information do you need to quote an MCC?
To quote accurately we need the motor list (kW rating, voltage, fixed-speed or variable-speed, duty), the I/O schedule, P&IDs, and the interface protocol for any package equipment or OEM controls. Site data such as 400V/50Hz/TN-S supply, IP rating (IP54/IP55 typical), enclosure preference and the required inspection/witness scope help us deliver a complete, build-ready proposal.
