16303-2

Terminal blocks are commonly seen in electrical and electronic equipment, and they are mainly divided into two categories according to their shape – power distribution terminal blocks and signal terminal blocks. 16303-2 is a type of power distribution terminal blocks used to split or distribute power to other equipment. This article will discuss the application field and working principle of 16303-2.

Application Field of 16303-2

16303-2 is widely used in industrial applications. It is especially suitable for applications with high safety requirements, such as railway vehicles, construction and engineering machinery, and other hazardous control circuit components. Moreover, 16303-2 can adapt to different types of wires and is suitable for a range of installation methods, making them the ideal choice for applications that require fast wiring and frequent maintenance.

Working Principle of 16303-2

16303-2 is designed with a two-level contact structure. The lower level contact is composed of a silver-plated precision contact spring and contact barrel, which are housed in a plastic enclosure. The upper level contact is composed of an insulated pad. The two contact areas are connected by an insulated contact bridge. When the terminal block is inserted, the contact springs inside the contact bridge interact with the contact barrel, providing a secure and reliable electrical connection. The spring contact has a high contact pressure and low electric resistance, providing reliable contact performance.

The upper-level mounting bracket provided by 16303-2 allows for safe and easy mounting. It can be easily mounted onto a mounting plate and then connected to the wiring ducts. Additionally, built-in safety features make 16303-2 suitable for applications where safety is a priority. The insulated contact bridge prevents sparking and conducts electricity safely, while the plastic enclosure prevents shorts and reduces the amount of heat produced.

Conclusion

16303-2 is a type of power distribution terminal blocks used in numerous industrial and hazardous applications. It allows for easy installation with its two-level contact structure and upper-level mounting bracket. Additionally, it is designed with built-in safety features for maximum safety in hazardous applications. 16303-2 is a great choice for applications with high safety requirements.
