Terminal blocks are a type of connector that enables quick connection and disconnection of electrical circuits. The ELFH0411G is a high current, space and cost saving terminal block developed by ERNI Electronics. In this article, we will discuss the application and working principle of the ELFH0411G.

The ELFH0411G terminal block is designed for high current applications. It is suitable for power supplies, industrial control systems, power electronics, and other applications where reliable electrical connections are required. The terminal block is available in two variations – a threaded type and a push-in type. Both variations are rated for currents up to 80A and have a voltage rating of 800V. The threaded variation also offers a higher rated current of up to 120A.

The ELFH0411G is made up of two sections – the header section and the plug section. The header section is the top part and is used for connecting a power source, such as a power supply or battery. The plug section is the bottom part and is used for connecting electrical devices, such as motors, lights, etc. The plug section is connected to the header section via a locking device, often referred to as a ‘key.’ This key fits into the header section and locks the plug section in place, ensuring a secure and reliable connection.

The pins on the plug section of the terminal block are designed to provide a reliable electrical connection. The pins are made from zinc-plated steel and are optimized for efficient electrical current flow. They provide superior contact force and minimize contact resistance. The pins also have a coating that is designed to minimize corrosion. Additionally, the plug section has a special design that prevents it from being locked in the ‘open’ position, ensuring a secure connection.

The ELFH0411G also has an integral strain relief feature. This feature allows the terminal block to be mounted and secured without the need for additional mounting hardware. The strain relief feature is designed to prevent mechanical pressure on the terminal block, improving the reliability of the connection. Additionally, it supports the use of a separate strain relief for higher current applications.

Finally, the ELFH0411G terminal block has a locking mechanism that prevents accidental disconnection. This feature is designed to ensure a reliable connection in any workplace. Additionally, the terminal block has built-in LED indicators to quickly identify any defective connections.

In summary, the ELFH0411G is a high-current, space-saving terminal block developed by ERNI Electronics. It is suitable for various high current applications, such as power supplies, industrial control systems, and power electronics, and is available in two variations – a threaded type and a push-in type. The terminal block has a special locking mechanism to ensure reliable electrical connection, as well as an integral strain relief feature and built-in LED indicators for identifying defective connections.
