Schneider AEG AS-J892-001 Switchgear Module
Schneider AEG AS-J892-001
AS-J892-001 is a low-voltage switchgear assembly (MLS) belonging to the Schneider AEG product line, adopting rear-mounted or top-mounted busbar structure. It is suitable for the main distribution or secondary distribution systems of power distribution networks, industrial plants and large-scale commercial buildings. Compliant with IEC 60947-1/2 standards, this product features high reliability and modular design, facilitating on-site expansion and maintenance.
Main Technical Parameters
Rated Voltage: 400V AC (Three-phase)Rated Current: 630A (400A, 800A optional)Short-time Withstand Current: ≥42kA (10kA ms)Circuit Breaker Type: Vacuum Circuit Breaker (VCB) or Air Circuit Breaker (ACB) optionalBusbar Material: Copper or aluminum, with rear-mounted busway designProtection Class: IP20 (Indoor use), IP54 protective enclosure optionalAmbient Temperature Range: -25°C – +55°CInsulation Class: Class B (Class H optional)
Product Features
- Modular Structure: Cabinets, busbars, circuit breakers, protection relays and other components adopt standardized modules, enabling quick assembly, disassembly and upgrade.
- High Safety: Equipped with overload, short-circuit and earth fault protection; visualized indicator lights and Human-Machine Interface (HMI) support remote monitoring.
- Flexible Installation: Base can be fixed by welding or M16 bolts; cabinet-to-cabinet connection uses M8 hexagon socket bolts, meeting diverse on-site layout requirements.
- Reliable Busbar Design: Rear-mounted busway allows easy maintenance; top-mounted busbar (MLS-600) is ideal for space-constrained scenarios.
- International Standard Compliance: Certified by IEC, EN and UL, meeting global market access requirements.
Structure & Composition
- Cabinet: Steel frame with reserved internal installation space; protective coating for enclosure optional.
- Busbar System: Copper or aluminum busbars in rear-mounted or top-mounted layout, equipped with busbar supports and fixtures.
- Circuit Breaker Module: Vacuum or air circuit breaker with mechanical operating mechanism and electromagnetic tripping device.
- Protection Relay: Digital or analog relay optional, realizing overcurrent, undervoltage, zero-sequence current protection, etc.
- Auxiliary Devices: Indicator lights, buttons, terminals, earthing bars, etc.
Typical Application Fields
- Main distribution cabinets for industrial substations and manufacturing workshops
- Power distribution systems for large-scale commercial complexes (shopping malls, office buildings)
- Power distribution and supply guarantee for public facilities like airports and ports
- High-reliability power distribution networks for data centers
Installation Key Points
- On-site Preparation: Ensure flat foundation and reserve sufficient space for cabinet handling and later maintenance.
- Fixing Method: Base can be fixed by electric welding or 4×M16 bolts; cabinet-to-cabinet connection uses 8×M8 bolts.
- Busbar Laying: Rear-mounted busbars need internal wiring inside cabinets, while top-mounted busbars have reserved channels on cabinet tops.
- Wiring Inspection: After primary main wiring completion, use insulation resistance tester to check insulation status, ensuring compliance with IEC 60947-1 requirements.
Maintenance Recommendations
- Regular Inspection: Conduct visual inspection and tightening for circuit breaker mechanical parts, contacts and busbar connections every 6 months.
- Cleaning & Dustproof: Keep cabinet interior free of dust and oil stains to prevent insulation aging.
- Functional Test: Perform full-system protection function test annually, including overcurrent, undervoltage and earth fault simulation.
- Spare Parts Management: Stock up on vulnerable parts such as circuit breaker contacts, springs and relay modules to shorten maintenance downtime.
