Product Overview
This series of power distribution units is an efficient, safe and modular electrical connection solution, specifically designed for achieving compact and orderly power distribution in control cabinets, distribution boards, motor drive centers and energy systems. It safely and reliably distributes the large current from a single power input to multiple branch circuits, significantly simplifying wiring, saving installation space, and enhancing the maintainability and safety of the entire electrical system.
Core features and advantages
Outstanding electrical performance
High current-carrying capacity: Utilizing high-conductivity electrolytic copper (or copper alloy) conductors, the rated current range covers from 30A to over 600A, meeting the demands of various industrial applications.
Low-impedance connection: The precise threaded holes and pressure plate design ensure the maximum contact area with the cable terminals, achieving extremely low contact resistance and voltage drop, and reducing energy loss.
High insulation safety: The housing is made of engineering plastics with excellent flame retardancy (such as PA66, PC) or high-performance bakelite, meeting the UL94 V-0 flame retardant grade, effectively preventing arc and short circuit risks, and providing comprehensive finger touch protection.
A sturdy and reliable design
Corrosion-resistant materials: The conductor parts are often treated with tin or nickel plating, providing excellent oxidation resistance and corrosion resistance, ensuring long-term stability and electrical conductivity.
Strong clamping force: Equipped with high-strength stainless steel screws and self-locking spring washers, it provides long-lasting and shock-resistant clamping force, preventing connection loosening caused by vibration or thermal cycling.
Modularization and scalability: The standard modular design allows for side-by-side installation, facilitating expansion. A variety of pole numbers (such as 1P+N+PE, 2P, 3P, 3P+N+PE, 4P, etc.) are flexibly selectable to meet the configuration requirements of single-phase, three-phase, and systems with neutral and ground wires.
Easy to install and maintain
Clear markings: Input/output ports, torque values, rated current and polarity are all clearly and permanently marked, facilitating quick and accurate installation and subsequent circuit identification.
Flexible wiring methods: Supports front-end or side-end wiring, compatible with ring crimp terminals, U-shaped terminals or bare wires (depending on the model), providing maximum flexibility for wiring inside the cabinet.
Space-saving: The compact industrial design optimizes the space utilization within the control cabinet, making the wiring neater and more orderly.
Typical application fields
Industrial automation: Power distribution for PLC control cabinets, motor drivers, and robot systems.
Electric power distribution: Switchgear, secondary outgoing lines of transformers, capacitor compensation cabinets.
Renewable energy: Photovoltaic inverters, wind power generation control systems, internal connections of energy storage battery cabinets.
Internal power distribution for mechanical equipment: CNC machine tools, packaging machinery, and printing equipment.
Infrastructure: Elevator control system, HVAC main control board, power distribution for data center cabinets.
