Barrier Terminal Blocks
A barrier terminal block is a connection terminal that is mounted individually in a hole drilled in a device panel or enclosure body, with the conductor clamped under a screw cap. It is used at output terminals where connections are frequently made and removed, such as power supplies, battery chargers, test and measurement setups and speaker outputs. This category includes Konsan medium-size transparent-type red and black barrier terminal blocks and a large-size black barrier terminal block. Choose according to the body size, the color that will distinguish the poles, the diameter of the panel mounting hole and the type of conductor or plug to be connected; verify the current and voltage rating from the manufacturer's data. By convention, a red body marks the positive terminal and a black body marks the negative terminal. A barrier terminal block is not a DIN rail terminal block lined up on a rail inside a panel; it does not distribute conductors in a row, and brings out a single connection terminal to the outside of the device.

How to choose Barrier Terminal Blocks
A barrier terminal block is a connection terminal that is mounted individually in a hole drilled in a device panel or enclosure body, with the conductor clamped under a screw cap. It is used at output terminals where connections are frequently made and removed, such as power supplies, battery chargers, test and measurement setups and speaker outputs.
- Clarify whether the task is connection, cable routing, enclosure distribution or termination.
- Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
- Choose housing material and pack quantity according to the mounting environment.
