The ATP-ST 4 compartment divider from Phoenix Contact, manufacturer number 3030721, is used for visual and physical separation of individual sections within terminal block or control panel installations. It is employed to clearly distinguish different circuits or functions within a common terminal field, thereby increasing the clarity and maintainability of the installation. The divider is specifically designed for use in industrial electrical installations where clear structuring of connections is required.

Compartment divider is the product type described here. It is a passive component inserted into existing terminal rows to create a visual and mechanical separation. The divider is finished in grey, allowing it to integrate optically neutrally into most control panel installations. Its dimensions are a depth of 39 mm, a width of 2 mm, and a height of 59.8 mm. These dimensions are aligned with standard terminal block dimensions, ensuring the divider fits easily into common mounting profiles.

Functions and equipment in detail include purely mechanical separation within a terminal row. The plate prevents cables or conductor connections from being accidentally routed into adjacent sections, thereby increasing the safety and error-free operation of the installation. The narrow width of 2 mm allows for compact placement without significantly increasing the overall width of the terminal row. The height of 59.8 mm corresponds to the standard height of terminal blocks, enabling flush installation.

Technology explained simply refers to easy mounting and use without additional tools. The divider is inserted into the designated mounting openings of the terminal row, where it is securely fixed by its shape and dimensions. It is a purely mechanical component with no electrical or electronic functions. The grey colour is standard in industrial electrical engineering and ensures uniform visual design.

Compatibility and accessories refers to use in combination with terminal blocks of the same series. The divider is designed for use in standard terminal block configurations, particularly in systems requiring modular division of circuits. There are no specific accessories associated with this divider, as it functions as a standalone component.

Mounting and installation are performed by simply inserting the divider into the designated mounting openings of the terminal row. The divider is inserted along the length of the terminal row, with its dimensions ensuring a stable fit that cannot be accidentally pulled out. No additional mounting aids or tools are required.

In operation the divider provides a durable and reliable separation within the control panel. Mechanical stability and precise fit ensure that the separation remains intact even during frequent maintenance work or mechanical stress. The grey colour supports visual order and facilitates identification of individual sections.
