Product Introduction: SUK-35 Screw-Clamp Terminal Block

Product Overview

The SUK-35 terminal block, featuring an innovative screw-clamp design, is engineered to deliver secure, low-resistance, and permanent electrical connections for a wide range of industrial and commercial applications. Compliant with international and national standards, it is ideal for connecting 0.75–50mm² round copper conductors (with or without tubular terminals) in AC/DC circuits, ensuring reliability and durability in demanding environments.

Technical Specifications

• Rated Voltage:
  • AC: 1000V (50Hz/60Hz)
  • DC: 125V
• Wire Compatibility: 0.75–50mm² round copper conductors (bare or unprocessed ends)
• Compliance Standards:
  • IEC 60947-1
  • GB/T 14048.1
  • GB/T 14048.7
• Material: Precision-machined brass clamping frame with self-locking mechanism.

Key Features

1. Self-Locking Brass Clamping Frame
   • Zero Mechanical Stress: The self-locking design prevents mechanical stress buildup, ensuring a gas-tight, low-resistance, and permanent connection.
   • Corrosion Resistance: Brass construction combined with precision engineering guarantees long-term stability in harsh conditions.
2. Reliable Connection for All Wire Sizes
   • Flat Clamping Surface: Securely grips even ultra-fine wires (from 0.75mm²) without slippage.
   • Anti-Oxidation Design: Transverse grooves on the conductive plate penetrate oxidized layers on wires, enhancing conductivity and pull-out resistance.
3. Maintenance-Free Operation
   • Stable Clamping Force: Rigid structure with minimal manufacturing tolerances ensures consistent, high-pressure contact.
   • No Post-Installation Checks Required: Designed for hassle-free, long-term reliability.
4. Versatile Wiring Solutions
   • Direct Connection of Soft Wires: Eliminates the need for pre-crimped terminals, saving time and costs.
   • Wide Application Scope: Suitable for industrial control systems, power distribution panels, and machinery requiring robust electrical interfaces.
