Terminal Blocks - Barrier Blocks

Terminal blocks and barrier blocks are essential components of any electrical system. They provide connections between two wires as well as insulation and are commonly used in industrial, commercial, and residential applications. Terminal blocks are typically used to connect wires to power sources whereas barrier blocks are used to panel mount components in an electronic system. YK5041623000G Barrier Blocks are specifically designed for applications that require high current density connection.

Construction of YK5041623000G

The YK5041623000G Barrier Block is a Din-rail mountable block constructed of a self extinguishing thermoplastic UL94V-2 rated material. It has an operating temperature range of 0 to 60°C and a voltage rating up to 380 VAC. It consists of four terminals, two of which can accept 18 to 14 AWG wires, each, and the other two can accept 12 to 10 AWG wires, each. The terminals are connected internally to two reinforcing bars, one above and one below the center of the block. The wires are inserted into the terminals and the screws are tightened, forming reliable connections. The terminals are also protected against thermal overloads with a fusible link feature.

Application Fields

The YK5041623000G Barrier Block is suitable for a wide range of applications. It is most commonly used in high-current applications such as motor circuits, home appliances, and other power supplies. It is also suitable for use in instrument and control panels, power distribution modules, and industrial applications which require high power solutions.

Working Principle

The YK5041623000G Barrier Block has a working principle that is based on the insertion and crimping of two wires into each of its four terminals. The terminals are often made of copper alloy, which can be crimped to create a secure connection. The two terminals are connected by two internal reinforcing bars that create a bridge and the sealed insulation between the two. Once the wires are inserted into the terminals and crimped, a conductive connection is established and the current is allowed to flow from the power source through the terminals and into the opposing wires. This provides reliable power distribution and the protection of the circuit from electrical shorts.In conclusion, the YK5041623000G Barrier Block is a reliable and cost-effective solution for a wide variety of high-current applications. It provides excellent electrical insulation and ample connection capabilities, providing users with peace of mind and ensuring reliable power distribution and circuit protection.
