Innovative Screw-Terminal Solutions with Enhanced Voltage Capacity – SUT series

ZHEJIANG SIPUN ELECTRIC CO LTD has launched a new series of screw-type terminal blocks, marking a significant upgrade in performance and versatility. Designed for industrial and energy applications, the SUT series introduces critical improvements, including a higher voltage rating of 1000V (compared to previous SUK series models) and enhanced compatibility with existing systems. Below is a detailed introduction to these cutting-edge products:


1. Core Features & Technical Advancements

  • Elevated Voltage Rating: The new SUT series supports 1000V rated voltage, significantly expanding its applicability in high-voltage environments such as rail transit, heavy machinery, and renewable energy systems.
  • Screw-Terminal Design: Utilizing robust screw-clamping technology, the terminals ensure secure connections for wire sizes ranging from 2.5 mm² to 10 mm², suitable for both low- and high-current scenarios. The design minimizes contact resistance and enhances long-term reliability.
  • Versatile Models:
    • General-Purpose Terminals: Includes models SUT-2.5, SUT-4, SUT-6, and SUT-10, catering to diverse wiring requirements.
    • Test Terminal (SUT-6S): Features a dedicated test port for safe voltage measurement and circuit diagnostics without disconnecting wires, ideal for maintenance and troubleshooting.


2. Compatibility

  • FBS Connector Integration: The SUT series is fully compatible with ST2/ST3 series components via standardized FBS connectors, enabling seamless integration into existing systems. This modularity reduces installation complexity and inventory costs.


3. Technical Specifications

  • Electrical Performance:
    • Rated Current: 24A (SUT-2.5), 32A (SUT-4), 41A (SUT-6), and 57A (SUT-10), ensuring adaptability to various power demands.
    • Insulation Material: PA66 (UL94-V0 rated), providing flame resistance and stability across a temperature range of -40°C to +105°C.
  • Mechanical Durability:
    • Screw Material: Brass, ensuring excellent conductivity and corrosion resistance.
    • Contact Plates: Red copper (pure copper), optimized for superior conductivity and oxidation resistance.


4. Target Applications

The SUT series excels in scenarios requiring robust electrical connections:

  • Industrial Automation: Secure wiring for control cabinets and machinery.
  • Renewable Energy Systems: High-voltage compatibility suits solar inverters and energy storage units.
  • Transportation Infrastructure: Rail and automotive systems benefiting from vibration-resistant connections.


5. Competitive Advantages

  • Safety & Compliance: Meets international standards for insulation (AC2000V/1min withstand voltage) and environmental resilience.
  • Cost Efficiency: Reusable FBS connectors and modular design lower total ownership costs.
  • Future-Proofing: Scalable architecture supports evolving industrial needs.
