Terminal Blocks - Barrier Blocks are widely used in industrial automation and power distribution applications.They are extremely compact yet robust, allowing them to easily accommodate a wide range of wiring configurations, including various wire sizes.

A21930509 is an integral part of the terminal block family. Its design features a 2-level construction to separate low-voltage and high-voltage circuits, eliminating the potential for electric arcs and ensuring extra safety. Its high performance complies with the requirements of the Classifications of Insulated Blocks and Quality Requirements (ICEA 107-212).

A21930509 terminals provide maximum versatility when it comes to attaching wires to the block. A variety of connection methods are available, including direct connection of wires to the block using removable set screws, and pressure compatible connections, which require no tools for installation. Moreover, the input and output connection points are clearly marked, providing greater visual appeal.

The working principle of A21930509 is similar to that of other terminal blocks. Electricity is routed through a single connection point and then distributed to several contact points of the block. The contact points are located within the block, between two layers of insulation. In order to ensure an optimal electrical connection, a spring-loaded mechanism within the contact terminals creates a firm connection between the wires and the block.

Apart from providing a secure and reliable electrical connection, A21930509 terminal blocks are also resistant to corrosion and spikes in voltage and current. The materials used in their construction are rated for 1000V or below and the terminal blocks are compact, allowing for easy installation into tight spaces.

A21930509 terminal blocks are suitable for a wide variety of applications, including industrial batteries, low voltage circuit breakers, generators, UPS systems, switchboards, solar inverters, power supplies, automation devices, and more. They are an ideal option for providing a fast and efficient connection between circuits in harsh industrial environments such as factories, warehouses, and plants. Their simple installation makes them easy to use, and their reliable construction ensures a long lifespan with minimal maintenance.
