£0.15
The Cembre 2046210, also identified as the RP-U3, is a premium pre-insulated fork terminal designed to provide secure, reliable electrical terminations for stranded copper conductors. As part of the trusted Cembre P Series, it is ideal for industrial control panels, switchgear, machinery, OEM equipment and building automation systems where dependable fork-type connections are required.
Manufactured from high-purity electrolytic copper with a minimum 3 µm tin-plated finish, the RP-U3 provides excellent electrical conductivity together with outstanding corrosion resistance. Its red halogen-free polycarbonate insulation incorporates a funnel-shaped conductor entry that simplifies conductor insertion while ensuring consistent, high-quality crimp connections.
Designed for conductor sizes from 0.25 to 1.5 mm², the Cembre 2046210 features a 3.2 mm fork opening (M3), allowing quick installation and removal without completely removing the fixing screw. It is supplied in packs of 100 terminals for professional electrical installations.
Fork terminals provide a practical alternative to ring terminals by allowing conductors to be installed or removed without fully removing the fixing screw. This reduces maintenance time while maintaining a secure electrical connection in control panels, machinery and industrial electrical systems.
The Cembre RP-U3 combines premium electrolytic copper with durable halogen-free insulation to deliver consistent crimp quality, excellent electrical conductivity and dependable long-term performance across demanding industrial environments.
