The Phoenix Contact D-ST 2,5-QUATTRO end cover is a precision-engineered accessory specifically designed to provide a secure and reliable closure for the ST 2,5-QUATTRO series of terminal blocks. This component is vital for maintaining the electrical safety and structural integrity of terminal assemblies mounted on DIN rails within industrial control cabinets and automation systems. By covering the open side of the terminal block, it ensures proper insulation and protects internal connections from environmental factors and accidental contact.
Advantages
This end cover offers a seamless fit that integrates perfectly with the modular design of the ST 2,5-QUATTRO series, ensuring that the assembly remains compact and organized. Its robust construction provides excellent mechanical stability, preventing the terminal blocks from shifting on the DIN rail. Furthermore, the use of high-quality insulating materials guarantees compliance with safety standards, effectively preventing short circuits and protecting users during maintenance or operation.
Suitable for
- Industrial control cabinet assembly
- Automation and process control systems
- Electrical distribution panels
- Modular DIN rail terminal block configurations
This component is not suitable for terminal blocks outside of the ST 2,5-QUATTRO series, as the dimensions and locking mechanisms are specific to this product line. It should not be used in applications where the terminal block is already fully enclosed or where the end cover would interfere with existing wiring paths or structural components.
Key specifications
- Compatibility: ST 2,5-QUATTRO series terminal blocks
- Material: High-grade insulating plastic
- Dimensions: 2.2 mm x 72 mm x 36.5 mm
- Mounting type: Snap-on
To install the end cover, simply align it with the open side of the last terminal block in your assembly. Apply gentle pressure until the snap-on mechanism engages securely with the housing of the terminal block. Ensure that the cover is flush with the side of the terminal to maintain the required insulation distance and structural alignment.
What to consider before purchase
- Verify the exact series of your terminal blocks to ensure compatibility
- Check the available space on the DIN rail for the additional thickness of the cover
- Ensure the environment meets the temperature and chemical resistance requirements of the material
For optimal safety and performance, always ensure that the end cover is firmly seated before applying power to the terminal assembly. Regularly inspect the assembly during routine maintenance to confirm that the cover remains securely in place.
