Insulating Body: IP Rating IP20, Flammability Rating UL94 V0

Component Specifications

Definition

The insulating body is a critical component of terminal blocks, designed to electrically isolate conductive parts while providing structural integrity and mounting support. It prevents short circuits, protects against electrical shock, and ensures reliable connections in various industrial applications.

Working Principle

The insulating body functions by creating a high-resistance barrier between conductive elements, preventing current leakage and short circuits. It maintains dielectric strength under specified voltage conditions while withstanding mechanical stresses and environmental factors.

Materials

Typically made from thermoplastics (e.g., polyamide PA6, PA66), thermoplastic materials (e.g., polycarbonate PC), or ceramic composites. Materials are selected based on UL94 flammability ratings (e.g., V0, V2), CTI (Comparative Tracking Index), and temperature resistance.
