WKDQ SAK Series Fuse Terminal Block Connector

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Electrical Connectivity: Equipped with brass contacts and screw connections, the WKDQ SAK Series provides reliable power distribution up to 500V. Adjustable metal clamps accommodate wires of varying diameters for versatile connectivity.
  • Fuse Integration: Designed with integrated fuse protection to safeguard circuits against overloads and short circuits, ensuring safety in critical electrical systems.

Key features

  • 1. Material Technology

    • With a corrosion-resistant brass contact and PA66 nylon housing, ensure reliable performance in harsh industrial environments. The brass material outperforms aluminum in conductivity and durability*, while PA66 provides superior heat and chemical resistance compared to standard plastics.

  • 2. Interactive Design

    • With adjustable brass clamps and screw connections, securely fasten wires of varying sizes (1-10 contacts) for easy installation and maintenance. The modular design simplifies integration into existing systems versus fixed-terminal blocks*.

  • 3. Performance Parameters

    • With a 500V rated voltage and multi-contact capability, handle high-power applications and complex wiring setups. Outperforms lower-voltage models in industrial-scale operations*.

  • 4. Scenario Solutions

    • With a protective cover and dust/moisture resistance, maintain reliability in both industrial and residential settings. The adaptable design supports diverse applications, unlike single-use terminal blocks*.

  • 5. Certification Standards

    • With RoHS, CE, and REACH certifications, meet global safety and environmental regulations. Ensures compliance in regions with strict standards versus uncertified alternatives*.

Supplier's note

  1. Technical Breakthroughs:

    • Brass Contacts: Triple the conductivity of standard aluminum alloys, reducing energy loss in high-current circuits.
    • PA66 Housing: 20% lighter than traditional ABS while maintaining thermal resistance up to 120°C.
    • Safety Cover: IP54-rated protection, surpassing industry-standard IP20 for dust and moisture resistance.

  2. Version Selection Guide:

    • Base Model: Optimal for standard industrial setups (e.g., HVAC systems) requiring up to 25A.
    • Advanced Model: Ideal for manufacturing plants needing +15% higher current capacity and extended cold-weather operation (-30°C).
    • Pro Model: Designed for extreme environments (e.g., mining, offshore platforms) with tripled insulation resistance and ultra-wide temperature tolerance.

With the Pro version’s -40°C rating, you can safely deploy in Arctic conditions while maintaining 500V performance. Pair its 32.5A capacity with the brass contacts to handle heavy-duty machinery without thermal degradation.
