Overview

The ABB 750J4-5 35kV 600 Series Deadbreak 4-Point Junction is a high-voltage electrical connector engineered for reliable, deadfront-rated terminations in medium-voltage distribution systems up to 35kV. This junction features a durable, molded rubber housing that encapsulates four connection points, ensuring environmental sealing against moisture, dust, and contaminants while providing electrical insulation rated for 35kV applications. The included stainless steel U-straps and back plate deliver robust mechanical stability and corrosion resistance, eliminating the need for additional mounting hardware or separate brackets. The deadbreak design allows for safe connection and disconnection under load without interrupting service, significantly reducing downtime during maintenance, reconfiguration, or emergency repairs. Designed for compatibility with the ABB 600 Series accessories, this junction is optimized for underground residential distribution (URD) systems, pad-mounted transformers, switchgear, and other medium-voltage applications where space efficiency and long-term reliability are critical. Its compact footprint and integrated mounting system simplify installation in tight enclosures, including vaults and cabinets, while maintaining full compliance with IEEE 386 deadbreak standards for safety and performance. The absence of a separate bracket streamlines installation and reduces potential points of failure, making it a dependable solution for harsh utility environments, including coastal areas with high salt exposure or industrial settings with elevated contamination risks. Trust ABB’s Installation Products for high-performance, field-proven solutions in medium-voltage distribution networks.
