Overview

The ABB CTL2502 is a Type CTL copper two-hole lug designed for medium-voltage electrical connections up to 35 kV. Constructed from high-conductivity wrought copper and finished with electro tin plating, this lug ensures reliable conductivity and corrosion resistance in demanding power distribution and transmission systems. The short barrel design accommodates wire sizes of 250 kcmil or 4/0 AWG, with a weld connection option for enhanced mechanical security. The 1/2-inch bolt size provides a secure mounting interface for busbars or termination points, distributing mechanical stress effectively. This lug is part of the Blackburn series of compression connectors, engineered for use in 600V to 35kV applications where circuit integrity is critical. The two-hole design stabilizes connections, reducing the risk of loosening under vibration or thermal cycling. Tin plating ensures long-term performance by protecting the copper conductor from environmental degradation, making it suitable for outdoor and industrial environments. The CTL2502 is a component for electrical distribution infrastructure, where reliable termination prevents failures in high-voltage systems.
