What Is a PTFIX Distribution Block?
PTFIX Distribution Blocks are modular terminal solutions designed for electrical potential distribution in control panels and cabinets. They come pre-assembled in multiple colors and sizes (4, 6, 12, or 18 terminals), supporting flexible installation and streamlined wiring.
Unlike traditional screw-type terminals that require torque adjustment, PTFIX blocks use push-in connection technology for tool-free wiring. These blocks save up to 50% panel space and reduce wiring time by up to 80%, presenting a significant advantage over traditional wiring methods.
By integrating a modular power distribution module into your control system, you can achieve consistent power delivery, easy maintenance, and a clean, professional cabinet layout.
How Push-in Technology Works in Distribution Systems
Push-in technology revolutionizes wiring by allowing direct, tool-free insertion of wires into the terminal block. This method relies on a precisely engineered spring inside the terminal. When a solid wire or a wire with a ferrule is pushed into the terminal hole, the spring automatically opens to accommodate the wire, then clamps it tightly to ensure a secure, vibration-resistant, and gas-tight connection. This eliminates the need for screws or any tools for standard connections—greatly reducing wiring time (up to 50% faster than traditional methods) and minimizing user error.
Key Working Steps:
- Direct Insertion: Rigid or ferruled wire is inserted straight into the terminal without tools. The force of insertion opens the spring, clamping the conductor as soon as it is fully engaged.
- Spring Clamping: The special steel spring applies consistent pressure to ensure a tight, conductive contact regardless of vibration or temperature shift. This uniform clamping force means electrical performance is stable and the possibility of loose connections is greatly reduced.
- Easy Release & Flexible Wires: For flexible wires without ferrules, a simple push-button or standard screwdriver is used to open the spring before inserting or releasing the wire. This design allows for both rigid and flexible wire types while keeping installation fast and error-free.
This tool-free connection simplifies installation, cuts labor costs, and delivers robust electrical performance even in demanding industrial settings.

Advantages of Modular Power Splitter Design
Modular power splitter design enables high flexibility, dense wiring arrangements, and easy expansion for future needs. PTFIX distribution blocks can be combined, customized, and mounted via DIN rail, direct, or adhesive methods, ensuring fit for all cabinet styles.
- Flexible Modular Expansion:
Multiple distribution blocks can be seamlessly joined together using plug-in bridges or tongue-and-groove connectors, allowing for quick system upgrades and customized layouts. - Three Mounting Methods:
PTFIX blocks support direct mounting via flange, DIN rail mounting (vertical and horizontal), and adhesive mounting. This adaptability ensures the blocks can be installed in virtually any control panel or cabinet without extra accessories. - Convenient Wiring:
Tool-free push-in technology makes connections fast and secure, and modules are pre-assembled—just unpack and connect. Color-coded terminal options further reduce wiring errors and speed up identification. - High-Density Layout:
Compact block sizes and side/top-entry designs enable more connections per unit area, maximizing space utilization in crowded control cabinets and supporting modern high-density wiring requirements.

FAQs of PTFIX Distribution Block
A1: A PTFIX distribution block is a ready-to-connect module designed for power distribution that uses push-in connection technology and supports DIN-rail or direct mounting. It differs from standard terminal blocks by offering integrated bridging, color-coded potentials, and compact design for space-saving cabinet layouts.
A2: PTFIX modules support multiple mounting options including standard DIN 35 rail, NS15 mini-rail, direct mounting via flanges, and even adhesive mounting in confined spaces — offering flexibility for control cabinets, machinery, or lighting systems.
A3: Depending on the model, PTFIX distribution blocks cover nominal cross-sections from 1.5 mm² up to 10 mm², rated currents typically around 17.5 A to higher values in larger versions, and support both rigid and ferruled conductors. For example, the PDF datasheet shows a PTFIX 12×1.5-NS15 version with rated current of 17.5 A.
A4: PTFIX blocks support plug-in bridges (accessories) that allow extension of potentials across multiple modules. You can snap blocks together and use bridge jumpers to distribute the same potential across many outputs without re-wiring individual connections.
A5: Yes. The modular distribution blocks in the PTFIX family are used in both AC and DC applications, for example 24 V automation systems or higher voltage power circuits. The specification sheets show rated voltages up to 500 V in some models.
A6: Key factors include:
- Required current rating and conductor size
- Number of output circuits needed
- Mounting type (DIN rail, panel, adhesive)
- Environmental conditions (temperature, vibration, hazardous zones)
- Accessories for bridging, marking and testing
Conclusión
PTFIX Distribution Blocks, designed for speed and reliability, are the preferred choice for modern electrical panel builders. With push-in connection and modular flexibility, they cut installation time, save space, and guarantee safe, high-performance wiring solutions.
