Product Description
RNB series non-insulated ring terminal is a bare round cold crimp lug made of high-purity red copper with tin-plated surface. Adopts one-piece seamless stamping process, smooth surface without burrs, high structural strength and excellent electrical conductivity.
Without insulating sleeve, it is suitable for installation in closed electrical boxes, distribution cabinets and metal grounding positions. The standard round ring hole fits bolt fastening perfectly, firm crimping, low contact resistance, anti-oxidation and high temperature resistant. Full international certifications support global wholesale, engineering matching and industrial power wiring.

Installation Diagram & Step Instruction
Step-by-Step Installation Diagram
Standard crimping steps for RNB non-insulated ring terminal. Professional operation ensures tight crimping and reliable electrical connection.
Strip appropriate wire insulation to expose complete copper core.
Insert the wire into the bare terminal barrel fully.
Crimp firmly with dedicated cold crimping pliers.
Fasten the ring terminal on the bolt with screw tightening.

Precautions
Select matched RNB model according to wire gauge and bolt diameter.
Use in enclosed insulated environment to avoid short circuit risk.
Avoid over-crimping to prevent terminal deformation and cracking.
Do not exceed rated current and voltage for load use.
