Custom Engineered Panel for Mining & Metals

Custom Engineered Panel assemblies for Mining & Metals deliver rugged, project-specific low-voltage switchgear designed to meet IEC 61439 requirements while addressing extreme environmental and electrical stresses found in mines, concentrators, smelters and rolling mills. Typical implementations combine Motor Control Centers (MCC), power distribution, motor starters (DOL, star-delta), soft-starters, VFD bays and protection/automation in a single lineup to save footprint and simplify installation. Common commercial references for industrial-grade solutions include Siemens SIVACON, ABB MNS and Schneider Prisma Set; custom assemblies integrate equivalent IEC 60947-compliant components selected for mining duty cycles. Design criteria include rated currents that are project-specific (examples: feeder/breaker frames 160 A–6300 A bus ratings), and short-circuit withstand ratings typically specified from 25 kA to 100 kA rms for 1 s depending on utility or generator fault levels. Rated voltages up to 1000 V AC are standard. Forms of separation per IEC 61439 (Form 1 through Form 4b) are applied according to safety and maintenance requirements; many miners choose Form 4b for segregation of bus, functional units and cable zones to reduce fault propagation and ease live-work policies. Environmental hardening is central: enclosures in powder-coated carbon steel, hot-dip galvanized or 316L stainless steel; ingress protection from IP20 up to IP66; ATEX/IECEx compliant solutions (IEC 60079) for gas/vapor zones; marine-grade paint and C5-M corrosion class for portside smelters. Thermal design accounts for ambient ranges commonly seen in mining (-40°C to +55°C) and altitude derating per IEC guidance, with forced ventilation, heat exchangers or heater/AC modules for VFD bays and battery cabinets. Protection and monitoring include IEC 60947-compliant MCCBs, fuse-switch-disconnectors, protection relays for earth-fault, overcurrent and transformer protection, arc-flash mitigation (arc-resistant layouts and blast relief), and integrated metering/energy management using CT/VT metering and IEC 61850 or Modbus for plant integration. Harmonic filtering and active front-end solutions are integrated where large VFD banks drive conveyors and mills. Manufacturing and validation follow IEC 61439-1/2 type and routine tests: dielectric, temperature-rise, short-circuit withstand, mechanical operation and IP verification. Real-world configurations: feeder/distribution switchboards feeding crushers and mills; generator-parallel panels with synchronizing and protection relays; mill MCC with segregated VFD compartments; remote substations with integrated LV distribution and telemetry. Patrion’s custom engineered panels are built to meet client fault level studies, SCADA interface, and site commissioning constraints, with full FAT documentation, test reports and optional third-party inspection to ensure compliance and operability in the most demanding mining & metals environments.
