Overview of the PTFIX 2.5 mm² Distribution Block
Il distribution block PTFIX 2.5 mm² series is a pre-assembled modular power node designed for fast, tool-free wiring in modern automation and control systems.
Each unit provides one power input and multiple outputs, ideal for distributing 24 V DC or low-voltage AC circuits in compact control panels.
Main Features:
- Conductor range: 0.5 – 2.5 mm² (AWG 20–14)
- Rated current: up to 24 A
- Rated voltage: 500 V AC/DC
- Push-in connection technology for tool-free installation
- Available in 4-, 6-, 12-, and 18-pole versions
Its plug-and-play design eliminates complex assembly, enabling installers to mount and wire immediately upon unpacking.
Push-in 2.5 mm² Connection Technology Explained
Push-in connection technology streamlines installation by enabling direct wire insertion without tools. Each PTFIX 2.5mm² terminal has a precision spring clamp, which holds the conductor tightly for stable, vibration-proof connections. This minimizes wiring time and ensures consistent assembly quality, even in high-density or hard-to-reach cabinets.
Vantaggi:
- No screwdrivers or torque tools required
- Faster wiring and rework (50–80 % time saving)
- Maintenance-free and safe under vibration
- Uniform clamping force for stable conductivity
