Schneider AEG M907-00

The M907-000 is a low-voltage switchgear belonging to the MLS series under Schneider AEG (now AEG Industrial Power). Adopting Factory Built Assembly (FBA), it is suitable for power distribution systems with 50/60 Hz, rated voltage ≤ 690 V and rated operating current ≤ 6300 A, providing functions of power distribution, conversion, control and reactive power compensation.

Main Technical Parameters

Structure & Composition

• Cabinet Shell: 2mm aluminum-zinc coated steel plate for the body, 1.5mm steel plate for door panels, epoxy powder coating (RAL 7035), with internal hinges and opening angle ≥ 120°.
• Protection Class: IP30/40 (ventilated), IP31/41 (drip-proof), upgradeable to IP42 and IP55; withdrawable units reach IP2XD in separated position.
• Busbar System: 3-phase 4-wire/5-wire, rear-mounted or top-mounted, dual-busbar (≥ 4000 A) design, equipped with PE protective conductors and vertical branch grounding busbars.
• Power Center: Including busbar compartment, equipment compartment and cable compartment; the busbar compartment can install horizontal or vertical busbars and accommodate up to 3 air circuit breakers.
• Motor Control Center: Provides fixed, plug-in and withdrawable units, with module height 8E/2 – 72E and rated frame current 160 A – 2000 A.

Installation & Maintenance Notes

• Installation Method: Wall-mounted (distance from wall ≥ 300mm) or free-standing (distance from wall ≥ 800mm); base can be fixed by welding or 4×M16 bolts; cabinet-to-cabinet connection uses 8×M8 hexagon socket bolts.
• Wiring: Primary main wiring schemes provide multiple busbar layout diagrams, supporting top or bottom incoming/outgoing lines; cables can be connected via prefabricated connectors or directly to terminal blocks.
• Protection Upgrade: Install shutters, sealed top plates or glass outer doors according to on-site protection needs to achieve higher grades such as IP42 and IP55.
• Daily Maintenance: Check bolt tightness, door lock sealing, busbar connections and protection class labels; regularly conduct functional tests and communication verification on air circuit breakers and molded case circuit breakers.
• Environmental Adaptation: Ensure the operating environment temperature, humidity and altitude meet product technical specifications; consult the manufacturer for type selection or take additional protective measures if exceeding the range.
