Cembre 2503315 (2A14-2M14) heavy-duty electrolytic copper compression ring terminal with two-hole palm and tin-plated finish for industrial power distribution and earthing applications.
£12.80
The Cembre 2503315, also identified as 2A14-2M14, is a premium heavy-duty copper ring terminal engineered for secure termination of copper conductors in industrial power distribution, switchgear and earthing applications. Manufactured from high-purity electrolytic copper with a protective tin-plated finish, it delivers outstanding electrical conductivity and long-term corrosion resistance.
Designed for demanding electrical installations, the 2A-2M series features a two-hole palm that provides superior mechanical stability compared with single-hole terminals. This makes it particularly suitable for installations subject to vibration, thermal cycling or high electrodynamic forces, while helping maintain a reliable low-resistance electrical connection.
The chamfered barrel allows straightforward conductor insertion before compression crimping, while the annealed copper construction ensures excellent deformation during installation using compatible Cembre tooling. Suitable for industrial control panels, substations, transformers, switchgear and medium-voltage systems up to 35 kV where applicable.
Heavy-duty copper compression terminals are designed to provide low-resistance electrical connections while withstanding significant mechanical and thermal loading. Their robust construction helps maximise system reliability in industrial power distribution and electrical infrastructure.
The Cembre 2A-2M series combines high-conductivity electrolytic copper, annealing and electrolytic tin plating to provide excellent electrical performance together with long service life in demanding indoor and outdoor installations.
