How to Choose the Right Terminal Block for Your Control Panel

A practical guide comparing COMBICON series terminal blocks. We help you select the perfect solution based on current, voltage, and application requirements.

Selecting the optimal terminal block is crucial for control panel safety, reliability, and density. Follow these key steps for the right Phoenix Contact solution:

1. Electrical Ratings: First, verify your current, voltage, and wire cross-section. The COMBICON series offers a complete range from signal-level to high-power applications.

2. Connection Technology: Choose based on your needs:

   • Screw Clamp: The versatile CLIPLINE complete system for universal use.

   • Spring Clamp: Ideal for vibration resistance and fast, tool-free wiring.

   • Push-in: Maximum installation speed for solid or ferruled conductors.

3. Pitch & Function: Select standard 5mm or compact 3.5mm pitch for space constraints. Enhance functionality with bridges, end barriers, and marking systems for efficient power distribution and clear identification.

By focusing on these criteria, you can leverage Phoenix Contact's modular system to build a safer, more efficient, and easier-to-maintain control panel.
