Component Specifications

Definition
A structural component used at the ends of terminal block assemblies to provide mechanical support, secure mounting, and proper termination of electrical conductors. It ensures alignment, prevents conductor displacement, and maintains electrical isolation between adjacent blocks.
Working Principle
The end plate/bracket functions by providing a rigid mounting point at terminal block ends, distributing mechanical loads, and creating a barrier to prevent accidental contact with live parts. It typically interfaces with DIN rails or mounting surfaces through integrated clips or screws.
Materials
Typically made from engineering thermoplastics (PA66, PBT, PC) with UL94 V-0/V-2 flame ratings, or metals (aluminum, steel with zinc plating) for high-strength applications. Material selection depends on dielectric strength, mechanical load, and environmental conditions.
Technical Parameters
  • Height Standard 45-90mm
  • IP Rating IP20 standard, IP65/IP67 optional
  • Width Range 6-12mm per terminal position
  • Mounting Type DIN Rail (EN 60715), Panel Mount
  • Current Rating Up to 300A
  • Voltage Rating Up to 1000V AC/DC
  • Temperature Range -40°C to +120°C
Standards
IEC 60947-7-1, UL 1059, EN 60947-7-1, DIN 46277

Frequently Asked Questions

What is the difference between an end plate and an end bracket?

End plates are flat components that cap terminal block ends, while end brackets typically have L-shaped or angled designs for additional mounting support. Both serve similar functions but differ in mechanical configuration.

Can end plates be used with any terminal block brand?

No, end plates are typically brand-specific due to dimensional variations in terminal block designs. Always verify compatibility with your specific terminal block series.

Are metal end plates better than plastic ones?

Metal end plates offer higher mechanical strength and better heat dissipation, while plastic plates provide better electrical insulation and corrosion resistance. Selection depends on application requirements.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
