Top 3 Customer Questions & Concerns ‍

1. Is the 4-pin model also 25A?

   • While most of this series is rated for 25A, some specific 4C (4-pin) variations may be rated at 10A. Always verify the specific marking on the block if your application requires the full 25A.

2. What wire size can these terminals hold?

   • The screw-down plates are designed to securely clamp a wide range of wire gauges, typically supporting 12 AWG to 22 AWG. For the most reliable high-current connection, we recommend using insulated crimp fork terminals.

3. Are the PCB pins strong enough for the weight of heavy wires?

   • Yes. These blocks are designed with heavy-duty metal pins meant to be soldered through the PCB. However, for very thick cables, it is best practice to provide external strain relief for the wires so they do not pull directly on the solder joints.
