Copper Core Options:
Available in two specifications: fully copper-clad and partially copper-clad. The fully copper-clad version features copper contact plates throughout, offering superior conductivity and lower heat generation; the partially copper-clad version provides better value for money while ensuring conductivity at the core contact points. The surface is nickel-plated to prevent oxidation and resist corrosion.

High Current Capacity, Safe and Reliable:
Available in 30A and 50A rated currents, suitable for automotive battery charging, power supply testing, and temporary wiring for high-power equipment. The clamping jaws provide strong grip, low contact resistance, and minimal heat buildup during prolonged use.

Two Jaw Widths for Flexible Clamping:

10mm Jaw Width: Suitable for clamping thin wires, small terminals, and PCB test points

20mm opening: Suitable for clamping battery terminals, thick cables, large terminals, and thick copper busbars
Choose based on your specific application for a more secure grip that resists slipping.

4mm plug-in design at the tail for quick wiring:
The tail features a standard 4mm banana plug socket (with a protective sleeve), compatible with common test leads, silicone-sheathed cables, speaker wires, and more. Wires can be connected via soldering or crimping, ensuring easy installation and plug-and-play functionality.

High-voltage insulation, safe and shock-proof:
The outer layer is wrapped in an insulating sleeve (made of PVC or silicone), featuring a high voltage rating to effectively prevent accidental short circuits or electric shocks. Red and black color-coding clearly distinguishes positive and negative terminals.

Applications:

Scenario    Recommended Specifications
🔋 Car/Motorcycle Battery Charging    50A-20mm (for thicker battery terminals)
🔌 Switching Power Supply Output Testing    30A-10mm (commonly used with thin wires)
📊 Temporary Wiring for Laboratory Instruments    30A-10mm (Highly versatile)
🚗 Automotive circuit repair, jump-starting    50A-20mm (High current + wide jaw opening)
🔧 Battery repair, inverter connection    50A-20mm
📺 Circuit board and small terminal testing    30A-10mm

⚠️ Note:

Ensure the current does not exceed the rated value during use, and avoid prolonged overloading.

Select the appropriate jaw size based on the diameter of the object being clamped.

Do not handle high-voltage circuits with bare hands in damp or flammable environments.
