Separation plate (terminal), Dark beige, Height: 79.05 mm, Width: 2 mm, V-0, Wemid, ZAP/TW 3 1608800000

Functional separation of circuits in control cabinets

The ZAP/TW 3 separation plate (cat. no. 1608800000) is a mounting element for Z-series terminal blocks, including ZDU and ZPE models with a cross-section of 2.5 mm². Its purpose is the physical and visual isolation of adjacent electrical circuits, which is necessary in cross-connected systems or when separating voltages of different potentials. In distribution cabinets, it eliminates the risk of short circuits between terminal block contacts and facilitates line identification during service work. The dark beige color contrasts with the metal DIN rail, improving the readability of the layout.

The product acts as a barrier dividing the mounting continuity within a terminal row and as an end plate closing the block from the side, protecting live parts from contact with tools. This construction allows for maintaining the required insulation distances (air gaps and creepage distances) in accordance with safety standards, which is crucial in high-density connections. By mounting the plate between circuits, the installer meets galvanic separation requirements without additional mechanical solutions.

Material construction and mounting mechanism

The element is made of Wemid plastic with a flammability class of UL94 V-0, meaning the material is self-extinguishing after the ignition source is removed - a standard required in control cabinets to minimize fire risk. The 2 mm thickness provides the rigidity necessary to maintain a stable position on the DIN rail under industrial vibrations. Dimensions: a height of 79.05 mm and a depth of 30.6 mm fit perfectly to the Z-series terminal profile, eliminating protruding elements that hinder cabling. The 2 mm width allows the barrier to be placed in minimal space between blocks. The material withstands temperatures from -50 °C to +120 °C (short-term up to 125 °C), enabling use in harsh outdoor conditions or near heat sources.

Mounting is performed via a snap-on system directly onto the DIN rail without tools. Mechanical clips ensure a stable connection to the 35 mm profile (EN 60715) and allow for easy disassembly during system reconfiguration. This design shortens installation time - simply press the plate until it clicks - and eliminates the risk of losing screws inside the cabinet. Precise fit of the clips guarantees that the element remains stationary even under intensive use of production machinery, protecting circuit sectioning throughout the device's life cycle without the need for additional tightening of fasteners during operation.

Technical application and system compatibility

The ZAP/TW 3 separation plate is primarily dedicated to ZDU 2.5/4AN and ZS12.5 S/LED modules, but it also works well with other Z-series elements of similar dimensions (e.g., ZPE 2.5). The installer can use this type of barrier in various configurations: from signal lines to motor control systems or building automation. In photovoltaics and industrial energy, where high DC or AC voltages occur, the visual and physical separation of circuits is crucial for personnel safety during live work or LOTO (Lockout-Tagout) procedures.

The ability to use the plate as an intermediate barrier (between blocks) or an end plate (at the end of the row) increases the flexibility of distribution cabinet design. This allows for the creation of modular sections with specific functions, e.g., separating input circuits from output circuits or isolating control from power in a single terminal row. A clear boundary between sections facilitates rapid identification of wiring errors before system startup - the installer immediately sees any potential mistakes when connecting wires.

The product complies with RoHS directive requirements and does not contain SVHC substances above the 0.1% weight limit, which is important for manufacturers of machinery exported to
