E/UK End Clamps (used in terminal block assemblies for electrical enclosures) come in different types based on their design, material, and mounting rail compatibility. They are essential for securing terminal blocks on DIN rails and preventing them from sliding out of place. Here are the common types:

1. Standard End Clamps

  • E/UK Standard Clamp: A widely used clamp designed to fit onto standard DIN rails (e.g., 35mm rail).
  • Used for general-purpose applications where moderate mechanical support is required.

2. Heavy-Duty End Clamps

  • Designed for applications where the terminal block assembly needs stronger mechanical support, especially for high-vibration environments.
  • They are bulkier and made from robust materials, like steel or reinforced plastic.

3. Miniature End Clamps

  • Compact clamps for small terminal blocks or confined spaces.
  • Suitable for light-duty applications.

4. Adjustable End Clamps

  • Feature an adjustable screw mechanism for more secure and precise clamping on various rail types.

5. Snap-On End Clamps

  • Simplifies installation with a snap-on mechanism.
  • Suitable for quick and tool-free mounting on compatible DIN rails.

6. End Clamps with Accessories

  • Some end clamps come with additional features, such as:
    • Integrated marking slots for easy identification.
    • Built-in grounding connections for safety compliance.

7. Material-Specific End Clamps

  • Plastic End Clamps: Lightweight and non-conductive, suitable for low-stress environments.
  • Metal End Clamps: Durable and heat-resistant, ideal for high-stress or high-temperature applications.
