2181990 Cembre A3-U4 COPPER TERMINAL

FORK TERMINAL - Cembre (A3-U4): Industrial-grade performance for demanding applications

A-U series terminals are made from electrolytic copper tape of more than 99.9% purity. They are the ideal choice for terminal connections of contactors, thermal relays, etc., fitted with captive screws. Thanks to silver alloy brazing and the process of annealing and electrolytic tinning, the connectors are easier to compress and more resistant to mechanical stress. Typical uses include control panels, switchgear, machinery and general electrical installations.
