We can inform you as follows:
For reference 33641, the following cable can be connected:
- 4 x 95...240 mm² Al/Cu
- Cables of class 2 and 5 are preferred for use with connector 33641.
Class 2 and Class 5 copper cables are compatible with the 33641 connector without ferrules. The use of ferrules is in fact forbidden. This is the way it has been tested.
Conclusion: The mentioned cable (class 5) is suitable for connection to reference 33641.
More information:
Cable classes refer to the flexibility of electrical conductors, as defined by standards like IEC 60228. These classes help determine how easily a cable can be bent or installed in tight spaces. Here's a breakdown:
🔌 Cable Classes According to IEC 60228
| Class | Name | Description |
|---|---|---|
| Class 1 | Solid conductor | A single, rigid wire. Used in fixed installations where flexibility is not needed. |
| Class 2 | Stranded conductor | Made of multiple wires twisted together. Less flexible than Class 5, but easier to handle than Class 1. Common in fixed wiring. |
| Class 5 | Flexible conductor | Made of finer strands than Class 2, offering high flexibility. Ideal for installations requiring frequent movement or tight bends. |
| Class 6 | Extra flexible conductor | Even finer strands than Class 5. Used in applications like robotics or portable tools where extreme flexibility is needed. |
🛠️ Use Cases
- Class 1: Electrical panels, fixed wiring in buildings.
- Class 2: Industrial installations, switchboards.
- Class 5: Machinery, flexible connections, control panels.
- Class 6: Robotics, audio equipment, moving parts.
