A terminal block is a type of insulated electrical connector used to securely connect two or more wires. They provide a safe and organised way to join wires in various circuits, making them essential in many electrical applications. Also known as terminal strips or connection blocks, they are widely used in industrial, commercial, and domestic settings.
Terminal blocks are often categorised by their termination type, which refers to the method used to connect the wires to the block. The choice of connection technology depends on factors like the application, environment, and the cable connector block requirements, such as conductor cross-section or AWG size. Our terminal blocks are available in several termination types, including:
Screw clamp terminals are the most common type. Wires are inserted into the block and pressed against a conductor strip. Tightening a screw then secures the connection.
Spring clamp terminals utilise a spring-operated mechanism to hold the wire in place. A screwdriver is used to open the clamp, allowing the wire to be inserted. Releasing the clamp securely grips the wire. These terminals are particularly well-suited for environments with high vibration.
Push-in connection technology allows for tool-free wire insertion. Simply push the conductor into the connection gap. These terminals accommodate both solid and stranded wires (with a ferrule). Their tool-free design ensures quick and easy installation.
RS supplies a wide range of high-performance terminal blocks to meet diverse needs. Our terminal connectors come in various types and connection methods. Some of the most popular include:
Terminal blocks are essential in various industrial applications where safe and reliable electrical connections are critical. Here are some common uses:
Choosing the right terminal block depends on several key factors. Consider the termination type (screw clamp, spring clamp, or push-in), the number of terminals, wire size, current and voltage ratings, and mounting style (DIN rail or panel mount). For specialised needs, explore options like fuse holders or pluggable connections using a terminal plug.
