Why Choose the Cembre 2320120 A37B-M10/24.5 Copper Tube Crimp Lug?
The Cembre 2320120, also identified as the Cembre A37B-M10/24.5, is a premium non-insulated copper tube ring terminal designed for terminating 185 mm² Class 5 and Class 6 flexible copper conductors. This specialist lug features an M10 fixing hole with a 24.5 mm offset palm, making it suitable for equipment where additional clearance or specific busbar spacing is required.
Manufactured from over 99.9% pure electrolytic copper, the terminal is annealed to maximise ductility during crimping and electro-tin plated to provide excellent protection against corrosion and oxidation. The result is a low-resistance electrical connection with excellent mechanical strength and long-term reliability.
The A37B-M10/24.5 incorporates a chamfered barrel entry and inspection hole to simplify installation and verify complete conductor insertion before crimping. It is ideally suited to switchgear, industrial control panels, power distribution systems and heavy-duty electrical installations requiring dependable high-current terminations.
