Overview

The ABB 750J3-5 35kV 600 Series Deadbreak 3-point Junction is a deadbreak connector designed for reliable medium-voltage cable splicing in industrial and utility applications. This junction includes a molded rubber housing for environmental protection, stainless steel U-straps for mechanical strength, and a back plate for structural integrity. The deadbreak design allows for safe connection and disconnection under load without interrupting service, making it ideal for maintenance and emergency repairs. The 3-point configuration supports multiple cable terminations in a compact footprint, reducing installation complexity. Compatible with 35kV class systems, this junction is commonly used in substations, switchgear, and underground distribution networks where reliable, long-term performance is critical. The absence of a mounting bracket provides flexibility in installation orientation, allowing for direct attachment to cable trays or structures. ABB’s 600 Series connectors are engineered to meet ANSI C119.4 standards for deadbreak devices, ensuring consistent performance in high-voltage environments.
