Schneider AEG MM-PMC1-300

Product Overview

Schneider AEG MM-PMC1-300 is a low-voltage switchgear cabinet under the AEG brand of Schneider Electric. This model belongs to the MMC (Modular Busbar Low-Voltage Distribution Switchgear) series, which is mainly applied in industrial automation, building power distribution and various power systems to realize power transmission, distribution, control and protection.

Key Parameters

AEG series products are available in multiple specifications (e.g. 300, 500, 800, etc.), so specific technical parameters (such as rated voltage, rated current, short-circuit breaking capacity) shall be confirmed according to the 300 specification. Common parameters are as follows:Rated voltage: 380V / 400V / 415V three-phase four-wire system (typical)Rated current: 400A-2500A (common range, subject to specific configuration)Short-circuit breaking capacity: Within 50kA generally (slight differences for specific models)Overall dimensions: Specific width, height and depth are subject to the model specification sheet

Product Features

• Modular design: Adopts modular structure with high internal space utilization, facilitating on-site secondary wiring and installation.
• Flexible wiring modes: Offers two structural options including rear busbar type (MLS) and top busbar type (MLS-600) to adapt to different installation environments.
• High safety performance: Equipped with multiple protection levels (e.g. MCCB, VCB, MSR, MCR) to ensure the safe operation of electrical systems.
• Strong compatibility: Supports various fieldbus protocols (e.g. CAN, Profibus, Modbus, Ethernet) for easy integration with PLC and upper computer systems.

Structure & Components

Referring to the structure of similar models (e.g. MM-FMC3-010), the equipment mainly consists of the following parts:

• Cabinet body: Formed by cold-rolled steel plate stamping with anti-corrosive paint on the surface.
• Busbar system: Copper or aluminum busbars fixed by elastic fasteners for quick assembly and disassembly.
• Functional modules:Accessories: Terminal blocks, grounding bars, cooling fans, door locks and fastener kits
  • Operation panel: Optional knobs, buttons or touch screens, used with indicator lights
  • Circuit breaker modules: Including moulded case circuit breakers (MCCB) and vacuum circuit breakers (VCB)
  • Contactor/relay modules: With auxiliary contacts
  • Measurement & protection modules: Including current transformers, voltage transformers, power meters, etc.
  • Control & communication modules: Including PLC, Ethernet, Profibus, Modbus, etc.

Application Fields

• Industrial automation: Power distribution and control for production lines
• Building power distribution: Main and secondary power distribution for large-scale buildings
• Infrastructure: Power distribution in airports, metro systems, hospitals and other places
• Energy management: Power access and management for renewable energy systems (e.g. photovoltaic systems)

Installation & Maintenance

• Installation: Generally installed on-site; cabinets can be fixed by welding or bolts, and internal modules adopt rail-mounted installation. Ensure the installation space meets heat dissipation requirements.
• Maintenance: It is recommended to regularly check the tightness of internal wiring, cleanliness of radiators, conduct functional tests on circuit breakers periodically, and ensure stable connection of communication modules.
