3. Product Features
- Modular Design: With a unit width of only 106 mm, multiple modules can be stacked side by side in the same cabinet to improve power distribution density.
- Rear-bus Structure: The busbar is located at the rear of the module, facilitating on-site quick wiring, maintenance and replacement, and reducing maintenance costs.
- High Short-time Withstand Capacity: The short-circuit capacity of 50 kA / 6 s meets the high-impact requirements of industrial sites.
- Flexible Combination: It can be freely combined with other Schneider AEG MM series (e.g., MM-P10-200, MM-P20-400) to form a complete power distribution system.
- Reliable Mechanical Structure: Fixed by 4 M16 bolts or welding; the connection between cabinets adopts 8 M8 hexagon socket bolts to ensure rigidity and vibration resistance.
- Compliance with IEC/EN Standards: Meets international safety and performance standards such as IEC 61439-1/2 and EN 60204-1.
4. Structure and Composition
- Housing: High-strength cold-rolled steel plate with spray coating for corrosion protection.
- Busbar System: Copper or aluminum busbar (optional), rear-mounted at the back of the module with quick-release buckles.
- Terminal Block: Screw-type terminals, compatible with conductors of various cross-sectional areas for convenient on-site wiring.
- Protection Devices: Optional thermal relays, overcurrent protectors or residual current protectors.
- Grounding Bar: Independent grounding bar, meeting IEC grounding requirements.
- Markings and Nameplates: Each module is equipped with clear electrical parameter markings for easy on-site identification.
5. Installation Points
- Cabinet Selection: Use distribution cabinets complying with IEC 60297-100 standard, with reserved sufficient width (≥ 106 mm) and height (≥ 305 mm) space.
- Fixing Method: It is recommended to fix the base with 4 M16 bolts to prevent the module from loosening in vibrating environments.
- Busbar Connection: After rear-mounting the busbar, fasten the busbar to the back of the module with special buckles or bolts to maintain good conductive contact.
- Wiring: Complete the connection between busbar and terminal block first, then conduct on-site conductor wiring; use insulating sleeves complying with IEC 60204-1.
- Protection: For humid or dusty environments, it is recommended to install protective covers or upgrade the protection class to IP54.
- Commissioning: Check the tightness of all bolts and terminals before power-on; use an insulation resistance tester to detect insulation status; conduct short-time withstand test for verification after completion.
6. Maintenance Recommendations
- Regular Inspection: Check bolt tightness, terminal block oxidation and busbar connection status every 6 months.
- Cleaning: Remove dust with a dry soft cloth; avoid using conductive cleaning agents.
- Replacement: Immediately replace components of the same specification if obvious wear or corrosion is found on terminal blocks or busbars.
- Record-keeping: Record the maintenance process in the power distribution system maintenance log for easy tracing and auditing.
