Top 3 Customer Questions & Concerns 🙋‍♂️

1. ⚡ Can I use this for 3-phase power applications?

   • Yes. With four pins, this block can comfortably accommodate a 3-phase connection plus a ground or neutral line, provided the voltage is within the 300V rating.

2. 🔧 What is the best way to ensure the wires don't vibrate loose?

   • For the most secure and professional fit, use insulated crimp fork terminals (U-type). These lock under the screw heads and work with the pressure plates to provide a vibration-resistant connection.

3. 💪 Are the PCB pins long enough for thick or double-sided boards?

   • The pins are designed with a standard length for through-hole soldering, providing ample reach for most standard and multi-layer PCBs while maintaining high mechanical strength.
