Terminal Blocks - Barrier Blocks are ubiquitous across industrial and consumer electronic applications, providing insulated connection and termination of wiring, as well as safe and easy transfer of electric current and signals. The A20720804R53 is a Barrier Block that provides a dependable and robust solution for wiring systems requiring multiple poles and levels.This product has a low profile terminal block system with high current-carrying capability that fits into the density range of Din-Rail mounting or wall-mount applications. It features a secure, integrated clip-on profile and a positive locking system that ensures maximum contact force and connection reliability. The product also operates with a high mechanical and electrical reliability and it offers excellent resistance to vibration. It is UL approved, and is able to bear a wide range of ambient temperatures with its thermoplastic housing.The application field of the A20720804R53 consists of solar systems, LED lighting fixtures, machine tools, industrial/control systems, motor control, power supplies and signal/data control. Its multiple level design has 6+PE terminals (6 poles and a ground/ Protective Earth terminal) that are used in different types of wiring systems.The working principle of this Barrier Block Model consists of two main stages: making a connection and making a disconnection. The connection is established through a simple arrangement that facilitates a rapid and secure connection. The secure mounting plate locks the terminals in place by snapping it onto the position above the terminals, while the cover locks and secures the insulation seals to the block. To disconnect, the process is reversed.The A20720804R53 is designed to tolerate high wattage loads and short circuit currents with its minimum contact resistance (2 mΩ max.) and high contact pressure.Overall, the A20720804R53 Terminal Block - Barrier Block is a low-cost, dependable solution with excellent mechanical and electrical reliability that is suitable for a range of applications requiring multiple poles and levels. It offers a simple arrangement for high current-carrying capability that fits into the density range of Din-Rail mounting or wall-mount applications. This product is UL approved and presents a secure connection that guarantees maximum safety.
