RICHGE Technology MDmax-ST Cabinet Accessories are a full range of supporting products specifically designed for ABB MDmax-ST intelligent low-voltage switchgear. As an industry leader with over 40 years of deep expertise in the low-voltage switchgear accessories sector, Richge leverages its independent R&D center, three intelligent production bases, and full-process quality control system. With the core advantages of "original factory compatibility, technical homogeneity, and quality consistency," MDmax-ST Cabinet Accessories have become the preferred supporting solution for industrial power distribution, commercial buildings, and other fields. Featuring modular design, high safety standards, and full-scenario compatibility, the products fully meet the installation, protection, and operation and maintenance needs of low-voltage switchgear across all
Leveraging Richge over 40 years of manufacturing experience in low-voltage switchgear accessories, the accessory products are custom-developed for the structural characteristics of MDmax-ST cabinets. All components have passed ABB’s original factory Type Test Authorization (TTA) and Richge "three-tier inspection process" (incoming raw material inspection, in-production random inspection, and full-performance factory inspection), ensuring 100% compatibility with ABB cabinets and enabling "plug-and-play" functionality.
Building on Richge technical accumulation in the low-voltage switchgear accessories sector — with a total of 78 national patents (including 12 invention patents) — the structural design patents for core products such as drawer operating mechanisms and busbar supports have been incorporated into the supporting technical specifications of ABB MDmax-ST cabinets, establishing Richge as a participant in formulating industry adaptation standards.
• Operating Mechanisms: Independently developed by Richge, including Type F Drawer Handles (Series 1050151/152/153) and Push-Pull Manual Operating Mechanisms (Series SUG-1-8E). Adopting a dual-patented design of "labor-saving lever + precise positioning," they are compatible with 1-3 unit drawers. With an operating torque ≤250N and a mechanical service life of up to 15,000 cycles (far exceeding the industry average), these products have been awarded ABB's "Best Compatible Component" certification.
• Support & Fixing Components: Richge ZMJ3 Series Vertical Busbar Supports, made of independently developed high-strength insulating material (incorporating arc-resistant and flame-retardant additives). Compatible with busbars of 6×30 to 6×100 specifications, they feature a short-time withstand current of 100kA and an insulation resistance ≥1000MΩ. All products have passed Richge simulated extreme condition tests (including -25℃ low-temperature and 70℃ high-temperature cycles).
• Panel Assemblies: Richge CFBK Series Flip-Open Control Panels, integrated with "tool-free disassembly + anti-misoperation locking" functions. Compatible with multiple installation specifications such as 8E/16E, the panels are made of Richge special flame-retardant engineering plastic (oxygen index ≥32) and comply with the UL94 V-0 fire protection standard.
• Door Locks & Hinges: Richge MLBK300522R/232R Series Door Hinges, made of 304 stainless steel (Richge custom-formulated alloy). With a load-bearing capacity of 80kg and over 50,000 fault-free opening/closing cycles, they are equipped with Richge segmented lockable design. Complying with the UL 489 safety standard, the products have obtained National Compulsory Product Certification (CCC).
• Insulation & Isolation Components: Richge EMC Electromagnetic Compatibility Side Panels, adopting a patented "multi-layer shielding + zoned isolation" structure. They achieve Category 4b separation as specified in GB7251.12 and are used in conjunction with Richge functional partition plates. With a fault arc interruption response time ≤0.8 milliseconds, the panels have passed CQC electromagnetic compatibility certification.
• Arc Flash Protection Accessories: Richge Sensor Mounting Brackets, custom-developed for the ABB TVOC-2 Arc Flash Protection System. Utilizing precision laser cutting (a core process of Richge intelligent production lines), the brackets feature a positioning error ≤0.5mm. Working in synergy with Richge arc flash barriers, they form a full-dimensional protection system.
• Cable Management Components: Richge Cable Glands, Guiding Accessories, and Cable Trunking. Adopting a "modular splicing + quick snap-on" design, they are compatible with the cabinet's IP54 protection class. Mass-produced at Richge Wuxi Intelligent Production Base (an intelligent factory with an annual output of 5 million sets of accessories), the delivery lead time is guaranteed to be ≤7 days.
• Fixing & Connecting Components: Richge Insert Nuts, U-Nuts, and Cabinet Joining Components. Featuring "hot-dip galvanizing + passivation" dual anti-corrosion treatment (Richge patented process), they withstand 500 hours of salt spray testing without rust and meet seismic grade 1-4 requirements for earthquake-prone areas (compliant with Telcordia GR 63-CORE standard). These products have been designated for use in multiple large-scale domestic substation projects.
• Auxiliary Accessories: Richge Door Control Switches, System Lighting Fixtures, and Earthing Accessories. All adopt a "universal interface + redundant design" and are compatible with other Richge low-voltage accessories, supporting post-installation cabinet expansion and upgrading. Exclusive Richge installation manuals (including 3D installation diagrams) are provided as standard.
