Schneider AEG MM-FMC3-010

1. Product OverviewThe MM‑FMC3‑010 is a Modular-Mounted Compact low-voltage switchgear of the Schneider AEG product line, engineered specifically for 400 V / 690 V three-phase four-wire distribution systems. Featuring a Rear-Mounted Busbar (MLS) structure, it enables high-density layout, flexible expansion and rapid on-site assembly. This switchgear is ideal for main distribution, sub-distribution and secondary control in scenarios such as industrial plants, building power distribution and energy stations.

• Rated Short-Circuit Current: 10 kA / 15 kA / 25 kA (optional)
• Rated Power: ≤ 45 kW (depending on specific module combination)
• Operating Temperature Range: -25 °C - +55 °C
• Protection Class: IP20 (internal) / IP54 (enclosure)
• Mounting Method: Wall-mounted, frame-mounted or base-fixed (bolted or welded)
• Module Dimensions: Unit width 300 mm, depth 400 mm, height 200 mm–800 mm (stackable)

3. Product Features

• Modular Design: Each functional unit (circuit breaker, contactor, relay, measuring instrument, etc.) is a standardized module, allowing quick on-site assembly or replacement and significantly shortening construction cycles.
• Rear-Mounted Busbar (MLS) Structure: Busbars are located at the rear of the cabinet, facilitating maintenance, reducing electromagnetic interference and providing better heat dissipation space.
• High Reliability: Equipped with low-voltage switching components compliant with IEC 60947‑4‑1 standard, it offers multiple protection functions including short-circuit, overload, undervoltage and undercurrent protection.
• Ergonomic Design: Comes with LED status indicators and optional touch operation panel, supporting local manual operation and remote digital control.
• Flexible Expansion: Secondary devices such as PLC, HMI and communication gateways can be added via DIN‑rail or plug-in backplane, achieving Industry 4.0 compatibility.
• Safety Protection: Complies with EN 60204‑1 (machine safety) and EN 61439‑1 (low-voltage switchgear assemblies) requirements, with protective door locks, grounding terminals and misoperation prevention design.

4. Structure and Components

• Cabinet Body: Stamped from cold-rolled steel sheet and coated with anti-corrosive paint on the surface.
• Busbar System: Copper or aluminum busbars, fixed with elastic buckles for quick disassembly and assembly.
• Functional Modules:Operation Panel: Optional knobs/buttons/touchscreens, paired with LEDs/indicators.
  • Circuit breaker modules (miniature air circuit breakers, miniature vacuum circuit breakers)
  • Contactor/relay modules (with auxiliary contacts)
  • Measurement and protection modules (current transformers, voltage transformers, power meters)
  • Control and communication modules (PLC, Ethernet, Profibus, Modbus)
• Accessories: Terminal blocks, grounding bars, fan radiators, door locks and fastener kits.
