YK4022803000G

Terminal blocks and barrier blocks are two common kinds of electrical connection products. YK4022803000G, as one of these products, is a standard vertical single-row barrier block. Typically, these kinds of barrier blocks are used in the field of automation control and in communication systems, including industrial automation control, communication control, fire alarm systems, variable frequency drive control, as well as power supply and signal control.

The YK4022803000G barrier block includes an insulating plastic base and terminals, as well as a connection bridge. The common voltage ratings of this block are 600 V and it can withstand temperatures from -25°C to +105°C. Its contact capacity is 22-14AWG and the insulation resistance is 500V. Its contact can be crimped, soldered, or screwed. Moreover, the YK4022803000G barreir block features a compact design and is safe and reliable.

The working principle of the YK4022803000G barrier block is fairly simple. The terminals are connected together in series inside the block, using the bridge connection. During operation, the current will flow from one terminal to the other in sequence. This principle is used to easily join the incoming current with the outflowing current and prevent any mismatch of cables. On a technical level, the five-contact design of the YK4022803000G creates a more reliable connection.

In addition, the terminals are installed extra-tight in the YK4022803000G, and the special insulation material is flame retardant, in accordance with UL94-V0. This ensures that the connection remains safe even during sudden current spikes. In addition, the junction of the bridge and the terminal ensures high performance, with a low contact resistance of around 3mΩ. This makes possible for the YK4022803000G to handle heavier current loads with greater power efficiency.

To sum up, the YK4022803000G barrier block is a robust, reliable and cost-effective device for heavy current applications. It is widely used in a variety of automation control and communication systems, due to its unique design and performance. Its five-contact design provides a more reliable connection and allows it to handle higher current loads without any issues.
