Cembre c250-12 Color Coded Ring Terminal

Product Description

The CEMBRE c250-12 is a color-coded ring terminal engineered for industrial electrical installations where connection reliability and conductor integrity are critical. Manufactured from electrolytic copper pipe with greater than 99.9% purity, the terminal undergoes annealing and electrolytic tinning to improve compressibility and increase resistance to mechanical stress. The collar features a chamfer and inspection hole that guides conductor insertion and prevents stretching of individual strands. Licensed electricians and industrial maintenance technicians are the primary installers for this type of lug.

The c250-12 is suited for control panels, switchgear assemblies, industrial machinery wiring, and general electrical installations where color-coded identification aids circuit organization and reduces wiring errors. The collar length is dimensioned to allow straightforward seating of the lug into compression tool dies, simplifying the termination process in high-density wiring environments. This terminal is appropriate for both new installation and retrofit work in demanding industrial and commercial settings.

Key Features

• Electrolytic copper construction with greater than 99.9% purity for high conductivity
• Annealed and electrolytically tinned for easier compression and corrosion resistance
• Chamfered collar with inspection hole to confirm full conductor insertion and prevent wire strand distortion
• Collar length optimized for proper engagement with compression tool dies
• Color-coded for fast circuit identification in panel and switchgear applications

Compatibility

Designed as an OEM-style compression ring terminal for use in industrial control panels, switchgear, machinery wiring, and general electrical installations requiring a tinned copper lug.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating any conductor. Use a calibrated compression tool appropriate for the terminal size to ensure a gas-tight crimp. Do not use open-barrel crimping methods on this type of closed-end ring terminal.
