The Phoenix Contact D-ST 6-TWIN (Order Number 3036767) is a specialized insulating end plate designed to terminate and protect the ST 6-TWIN feed-through terminal block series. Serving as a critical safety barrier in electrical control panels, the D-ST 6-TWIN provides the necessary insulation at the end of a terminal strip to prevent accidental contact with live conductors and to isolate the assembly from adjacent components or grounded metal surfaces. Manufactured from high-grade Polyamide (PA), this component ensures that the integrity of the installation meets rigorous international safety standards, including UL 94 V0 flammability ratings.Engineered for harsh industrial environments, the 3036767 end plate operates reliably across an extreme temperature range, from -60°C to +130°C (relative temperature index). This makes the Phoenix Contact D-ST 6-TWIN suitable for applications ranging from frozen logistics centers to high-heat manufacturing floors. Its robust construction not only acts as a physical stop but also provides the necessary creepage distances required for maintaining voltage isolation up to 550V within the panel. The “Twin” designation indicates its specific compatibility with the double-level terminal blocks, ensuring a perfect mechanical fit that seals off the internal spring-cage mechanisms from dust and debris.For system integrators and panel builders, the D-ST 6-TWIN is an essential accessory that completes the professional finish of a wiring cabinet. It snaps securely onto the DIN rail profile, locking into place alongside the terminal blocks. By using the genuine Phoenix Contact 3036767, engineers ensure that the modular system maintains its certified electrical characteristics, preventing potential short circuits and ensuring long-term reliability in compliance with railway (DIN EN 45545-2) and general industrial safety codes.

Main Features and Advantages
Superior Material Properties:
The Phoenix Contact D-ST 6-TWIN is molded from high-quality Polyamide (PA), a material chosen for its exceptional mechanical strength and thermal stability. Unlike cheaper PVC alternatives, the PA used in the 3036767 offers excellent resistance to aging and UV radiation, ensuring it does not become brittle over years of service. The material is rated UL 94 V0, meaning it is self-extinguishing and will not propagate a flame in the event of an electrical fault, a critical feature for protecting high-value assets in automation cabinets.
Precision Fit and Safety:
Designed specifically for the ST 6-TWIN series, this end plate ensures a precise, gap-free closure at the end of the terminal row. The D-ST 6-TWIN effectively prevents tools or loose wires from accidentally touching the side of the last terminal block, eliminating the risk of short circuits to ground or adjacent phases. Its slim 2.2 mm width allows for maximum space efficiency on the DIN rail, allowing more circuitry to be packed into limited enclosure space without sacrificing safety clearance.
Extreme Environmental Tolerance:
Industrial facilities often experience wide temperature fluctuations. The Phoenix Contact D-ST 6-TWIN is tested and certified to withstand static applications at temperatures as low as -60°C and continuous electrical stress up to 130°C. This wide operating window makes the 3036767 a reliable choice for outdoor enclosures, refrigeration units, or near heat-generating machinery where standard plastic components might warp or crack.
Regulatory Compliance:
Using the D-ST 6-TWIN helps maintain the overall certification of the control panel. It complies with stringent railway fire protection standards (DIN EN 45545-2), covering aspects like smoke density and toxicity. For OEMs building equipment for mass transit or heavy industry, specifying the Phoenix Contact 3036767 simplifies the compliance process by ensuring every component on the rail meets the highest safety benchmarks.
Application Field
Control Cabinet Manufacturing:
In the production of PLC and DCS control cabinets, the D-ST 6-TWIN is used to terminate rows of signal and power terminals. It provides a neat, uniform edge to the installation, improving the aesthetic quality of the panel while ensuring that the high-density wiring typical of modern automation systems remains safely isolated from the cabinet walls and other conductive parts.
Railway and Transportation:
Due to its compliance with DIN EN 45545-2 (HL 1 – HL 3), the 3036767 is extensively used in rolling stock applications. Whether in traction converters or signaling distribution boxes, the Phoenix Contact D-ST 6-TWIN contributes to the fire safety strategy of trains and metros, resisting ignition and minimizing toxic smoke emission in the event of a catastrophic failure.
Renewable Energy Systems:
In wind turbine converter cabinets, where vibration and temperature cycling are common, the D-ST 6-TWIN secures the ends of terminal strips carrying sensitive control signals. Its robust locking mechanism prevents loosening due to vibration, ensuring that the insulation barrier remains intact throughout the turbine’s operational life.

Installation and Maintenance
Pre-installation preparation:
Before installing the Phoenix Contact D-ST 6-TWIN, ensure that all terminal blocks in the row have been properly seated on the DIN rail. You do not need special tools for the end plate itself, but having a small flathead screwdriver can help if you need to adjust the position of the adjacent terminal. Verify that the orientation of the terminal row matches your schematic; the D-ST 6-TWIN should be placed on the side where the conductor entry is finished, effectively capping off the assembly. Ensure the DIN rail is clean and free of metal shavings that could impede the snap-on mechanism.Maintenance recommendations:
During routine maintenance shutdowns, inspect the D-ST 6-TWIN for any signs of physical damage, such as cracks or discoloration, which could indicate overheating or UV degradation. Although the 3036767 requires no torque checks, ensure it has not been dislodged by vibration or accidental impact. If you are expanding a panel and removing the end plate, check the mating surface of the terminal block to ensure no debris has entered the housing before re-installing the Phoenix Contact D-ST 6-TWIN. Always replace damaged end plates immediately; they are a primary line of defense against accidental contact.
