Copper Tube Terminals — DT-2 Series
Heavy-duty copper tube terminals with rigid two-bolt mounting for anti-rotation and firm contact.
Tin-plated copper barrel ensures low resistance and corrosion protection.
Full coverage from DT-2-10 to DT-2-400 with complete D/d/L/W metrics for precise die matching.
Reliable choice for switchgear, control panels, battery and general power-distribution terminations.
Overview — Copper Tube Terminals
The DT-2 Series are heavy-duty copper tube terminals using a two-bolt palm to
provide anti-rotation stability and enlarged contact area on busbars and panels. The tin-plated copper barrel
delivers low contact resistance and dependable performance in industrial power-cable terminations.
Material: Tinned Copper |
Structure: Two-bolt palm |
Crimp Profiles: Hex / Indent / Compression |
Range: DT-2-10 ~ DT-2-400
Applications
- Battery and DC power distribution
- Switchgear, control panels, UPS cabinets and busbar terminations
- Industrial installations requiring secure two-bolt mounting of copper tube terminals

* Dimensions are typical DT-2 datasheet values. Verify conductor class and crimp die compatibility before installation.
Installation Notes
- Strip conductor to length and ensure full insertion before crimping.
- Crimp using the matched die (hex / indent / compression) to reach rated pull-out strength.
- Tighten both bolts to the specified torque for optimal contact and stability.
