Discover the Benefits of Using Snap-On Type Grounding Terminal Blocks in Electrical Circuits
September 2023

In the power industry, ensuring the safety and reliability of electrical circuits is of paramount importance. Grounding is an essential aspect of electrical installations, and it is crucial to ensure that every electrical component is adequately grounded to prevent any damage or harm to people or equipment. To achieve effective grounding, the use of high-quality components is essential. In this blog post, we will explore the benefits of using snap-on type grounding terminal blocks in electrical circuits. These innovative components offer numerous advantages over traditional grounding methods, providing enhanced safety and efficiency in power systems.


What are Snap-On Type Grounding Terminal Blocks?

Traditionally grounding connections in the electrical cabinets are often made with the help of bus bars with tappings made using screws and lugs. This mechanism has a high rate of failure on account of the fact that it relies heavily on the workmanship of the cabinet wiring technician. These were replaced to a great extent with Terminal Blocks that allowed for grounding connections to be made with the aid of an internal screw and grounding foot.  However these too have a chance of failure as it depends on the wiring technician to remember and effectively tighten the grounding screw of the terminal block.

Snap-on type grounding terminal blocks are specialized electrical components used in power systems to provide secure grounding connections without the dependence on the skill and care of the electrical cabinet wiring technician. These terminal blocks are designed with a unique snap-on mechanism that allows for easy installation and removal without the need for additional tools or complex procedures, all the while ensuring that there is a 100% error free gouring connection established. Snap-on type grounding terminal blocks offer numerous advantages which are further enumerated below.




Key Features of Snap-On Type Grounding Terminal Block:

Secure Connection: 

Snap-On Type Grounding Terminal Blocks ensure a reliable and secure connection by two means. Primarily when they are snapped on to the DIn Rails they establish a reliable earthing connection to the DIN rail because of their specially designed alloy feet. Also the time tested screw clamp mechanisms that Connectwell Earthing Terminal Blocks carry ensure that a gas tight electrical connection is established when the wires are clamped in them. The Connectwell Screw Clamp design offers optimum contact force and requires no maintenance. Both of these aspects ensure a consistent and reliable ground connection, which is critical for the safe operation in Electrical circuits.



Easy Installation: 

Snap-on type grounding terminal blocks are designed for effortless installation. Their design enables intuitive usage which ensures a quick and secure mounting on DIN rails in control panels. The snap-on feature eliminates the need for additional tools or complex procedures, reducing installation time and effort. With a simple push or snap action, the terminal block securely attaches to the mounting rail quickly and reliably.



Range of Conductor Sizes: 

These grounding terminal blocks are designed to accommodate different conductor sizes, ranging from small gauge wires to larger cables. This versatility allows for easy integration into diverse electrical circuits, ensuring compatibility with various grounding requirements.



Robust Construction for increased durability:

Snap-on type grounding terminal blocks are constructed using high-quality materials that offer excellent mechanical strength and durability. This robust construction ensures long-term reliability, even in demanding environments. 





Electrical Contact Reliability: 

These terminal blocks are engineered to provide reliable electrical contact. They are designed to handle high electrical currents without compromising safety or causing arcing. The secure connection minimizes the risk of accidental disconnection, providing enhanced safety in electrical systems.




Ease of Maintenanceand Expansion of Electrical Circuits:

Maintaining and troubleshooting electrical systems is a routine task in the power industry. Snap-on type grounding terminal blocks simplify maintenance operations, allowing for easy removal and replacement when necessary. Their modular design facilitates efficient circuit modifications or expansions without disrupting the entire system.




Versatility in applications across industries:

These grounding terminal blocks are highly versatile and can be used in a wide range of electrical circuits across various applications and industries. This is enabled by the fact that these Terminal Blocks are modular and available for a variety of conductor sizes.



Snap On Type Terminal Blocks are the result of constant evolution in electrical component design. They not only ease the installation and maintenance of control and power cabinets but also substantially enhance the safety levels in electrical circuits.
