Bimetallic Lug Connector
This bimetallic lug facilitates the connection of aluminum cables to copper ends in low-voltage electrical equipment. It features a friction-welded structure and a narrow palm design, making it suitable for equipment with limited contact space.
Technical Specifications
Overview
High-Performance Bimetallic Connection
The CALB-N series bimetal lugs are engineered for reliable transition connections between aluminum or aluminum alloy cables and copper electrical equipment terminals. Featuring a friction-welded construction, these lugs ensure a robust mechanical and electrical bond while preventing galvanic corrosion between dissimilar metals. The narrow palm design is specifically optimized for space-constrained installations such as MCCB and motor connections.
