Terminal blocks can be used to join two wires often supplying power to electrical components such as lamps or motors. Barrier blocks refer to a type of terminal block that provides physical separation between each wire. This article will cover the application field and working principle of the A307105S2422 terminal block.

Applications

The A307105S2422 terminal block fits into the barrier block category as it is DIN-Rail mounted with interlockable terminal blocks and a five point connection. It has a white finish and is suitable for 24 – 15 AWG wire sizes and is certified for UL, CSA, and TUV standards. These blocks are popular in industrial connections as they are designed to stand up to demanding conditions. Typical applications include wiring up inside machines for electronic control panels, motor wiring, automotive applications, instrumentation, lights, and industrial controls.

Working Principle

The A307105S2422 terminal block has a five point connection from each terminal. This means that when two wires are connected to each terminal, a total of five contact points form the connection, ensuring an effective and secure connection. The contacts are silver-plated and the base is constructed from a moulded plastic.The A307105S2422 terminal block also includes terminal screws that are tightened to secure the connected wires. The rule of thumb is to torque the screws to 0.5–0.7 newton-meters, or 5–7kg-meters, depending on the application. Correctly tightened screws will ensure reliable and safe operation of the connection.

Benefits

Barrier blocks like the A307105S2422 are especially useful for twin wiring applications. Twin wiring is when multiple power supplies are connected, for example in the case of a dual voltage lamp, or two motors that are connected together.The barrier block allows you to keep the supplies separate from each other while maintaining the same five point connections for each and ensuring secure connections. This type of block is also more likely to stay intact during rougher industrial applications and can prevent electrical short circuits that can occur with traditional terminal blocks.
