Overview

The ABB DKB 2 N is a disconnectable transformer adapter connector designed for industrial transformer installations requiring secure, removable connections. Constructed from durable aluminum, this keebar features a tapped 1-14 UNS-2B thread with left-hand threading for compatibility with standard transformer studs and adapters. The unit measures 3-1/2 inches by 4-39/64 inches with a 3/8-inch mounting pad, providing a stable base for secure attachment. Two rows of 2 9/16-inch holes spaced 1-3/4 inches apart allow for flexible mounting options, accommodating various transformer configurations. The included pink insulating compound and cap ensure reliable electrical insulation and protection against environmental contaminants, while the 5/8-inch stud adapter expands compatibility with larger transformer studs. This adapter is ideal for medium-voltage transformer applications where disconnectability and ease of maintenance are critical. The left-hand threading prevents accidental loosening under vibration, a common requirement in industrial environments. The aluminum construction offers a balance of strength and corrosion resistance, making it suitable for both indoor and outdoor installations. The UNSPSC code 39121443 classifies this as a transformer connector, confirming its role in electrical distribution systems.
