A10420607R26 is a range of terminal blocks, also known as “barrier blocks”, used in electrical connection and distribution systems. A terminal block is a type of electrical connector that is used to connect two or more wires, typically of different currents, into a single device.

Application Field

Terminal blocks have been used for many years to connect low voltage circuits, and are an essential component in many switchgear and automation systems. Common applications include industrial control, electrical motors, transformer protection systems, power distribution systems, and panel wiring. These products can also be used for other applications, such as power converters, instrumentation systems, communication systems, and HVAC systems.

The A10420607R26 terminal blocks offer a choice of single phase, three phase or single-phase-to-three-phase power, as well as a selection of standard and advanced accessories, such as metal bridges, spring-loaded terminal pins, terminal covers and locking clips. By providing a diverse range of products, the A10420607R26 series ensures compatibility for any need and application.

Working Principle

The A10420607R26 terminal blocks employ a simple yet effective design. Each product consists of a two-part terminal block with two opposing pieces. Each piece has a set of terminals, with two or more spring-loaded contact pins. When the two pieces of the block come together, the spring-loaded contact pins penetrate the insulation of the wires and make the connection. The terminals also have two tabs that fit into slots in the bottom part of the terminal, providing added security and stability.

In addition, the A10420607R26 terminal blocks also feature two locking clips that are used to secure the connection. These clips can be removed, allowing for easy installation and disassembly of the terminal blocks. This makes these terminal blocks ideal for applications where frequent reconnection is required.

The A10420607R26 terminal blocks offer a simple and reliable way to connect power supplies, load circuits, and other electrical systems. With a variety of sizes and configurations available, they are sure to meet any application requirement, and are an essential part of many electrical systems.
