Spring Quick Connector for Safe and Fast Electrical Connections

Electrical terminal block

The screwless lever-type electrical terminal block is the ideal solution for making quick, safe, and highly professional connections in any domestic or technical system. Its lever mechanism allows you to lock the cable in an instant, without the use of tools and without the risk of damaging the conductor. This system significantly reduces wiring time and ensures a stable, long-lasting connection. Compatible with rigid, flexible, and multi-stranded cables with cross-sections between 0.08 and 2.5 mm² , the terminal block is available in 2-pole, 3-pole, 4-pole, and 5-pole versions, allowing it to easily adapt to any system configuration. The structure, featuring groups of interconnected holes, allows for inputs and outputs to be managed in the same pole, facilitating branch connections, series connections, and extensions without the use of additional external components. The clearly identified levers (phase, neutral, earth, or dedicated numbering) make installation more intuitive and reduce the risk of errors during assembly. The compact design allows for installation in 503 junction boxes, electrical panels, suspended ceilings, and light fixtures with limited space, maintaining a clean and tidy wiring environment. It also includes a snap-on fastening and J-pin , which allows the terminal block to be installed without screws on dedicated supports, ensuring stability and facilitating disassembly for maintenance. The push-button quick-release system makes cable removal simple and controlled, an essential advantage during subsequent interventions or system modifications. This terminal block is not only perfect for LED lighting, but is also a versatile choice for any low-voltage electrical connection: sockets, transformers, power supplies, electrical panels, smart devices, and home automation systems , always offering maximum safety and reliability.

Interconnected Hole Groups for a Neat and Secure Connection

Each terminal block pole is composed of a group of interconnected holes , designed to manage the connection of the conductors in a simple and orderly manner. The internal structure allows the cable to be inserted through the upper holes, while the lower part acts as a technical support and contributes to the stability of the clamping. The configuration of the groups allows for incoming and outgoing connections within the same pole, facilitating any branches or extensions of the circuit without the need for additional external terminals. This solution keeps the wiring clean and compact, reducing the space occupied in the junction box or at the light point. Once the conductor is inserted, the internal mechanism locks the cable firmly and prevents accidental disconnection, ensuring a safe and reliable connection in any configuration: 2-pole, 3-pole, 4-pole, or 5-pole . Each pole is designed to correctly manage the conductors associated with its circuit (phase, neutral, or return), maintaining clear separation and reducing the risk of errors during installation. Thanks to this modular and interconnected structure, the terminal block allows for tidier wiring, more versatile functions and more efficient conductor management, regardless of the number of poles chosen.

Front and Rear Holes

The terminal block features three front holes , designed to securely connect both rigid and soft (flexible) cables. This side is the main conductor insertion side and ensures a stable and immediate clamping. On the rear side, however, the ability to connect soft cables depends on the presence of the three-hole button : when installed, it allows the connection of both types of cable; without the button, the rear side can only accommodate rigid cables. At the bottom, there is a J-shaped pin , designed to secure the terminal block without using screws. This system makes installation quicker and disassembly much easier.

Quick Release System with Push Button

The terminal block features a convenient push-button quick-release system that allows for quick and easy cable removal without damaging the conductor. By pressing the button on the top, the internal spring opens and the cable can be extracted effortlessly, making maintenance much quicker than with traditional terminals. If the cable has been inserted from the opposite side, which lacks a button, it can still be released thanks to the special T-shaped hole , into which a small tool can be inserted to unlock the clamp. This dual system ensures versatile use and extremely convenient wiring management, especially in small spaces such as junction boxes or light fixtures. The push-button mechanism ensures controlled release, protects the conductor, and facilitates future maintenance, offering a professional, safe, and long-lasting solution for any type of electrical installation.

Compatibility with Rigid and Flexible Cables

The terminal block is designed to accommodate a wide range of conductors, making it extremely versatile in any electrical system. It is compatible with solid (single-strand) and flexible (multi-strand) cables with cross-sections ranging from 0.08 mm² to 2.5 mm² , always ensuring a stable and secure connection. The internal locking system applies uniform pressure to the conductor, ensuring reliable contact and reducing electrical resistance. This allows it to be used in a variety of applications such as lighting points, electrical panels, branches, smart devices, and general connections, always maintaining maximum safety and electrical continuity.

Frequently Asked Questions

1. What kind of cables can I use with this terminal block?

The terminal block is compatible with rigid, flexible and multi-strand cables with a cross-section from 0.08 to 2.5 mm² , always guaranteeing stable and secure clamping.

2. Do the different versions (2, 3, 4, 5 poles) have different functions?

No, all versions work the same way. Only the number of poles changes, allowing you to connect 2, 3, 4, or 5 separate lines depending on your system's needs.

3. Is it only suitable for LED lighting?

Absolutely not. It's perfect for LEDs, but can also be used for sockets, transformers, power supplies, electrical panels, branch circuits, smart devices, and home automation systems .

4. Do I need a tool to insert or remove the cables?

No tools are required to insert the cables. To remove them, simply press the lever in the push-button versions. In the versions without a push-button, a small tool can be used in the dedicated hole.
