Abb ATL250-12 Aluminum Compression Lug 250 Kcmil

Product Description

The ABB ATL250-12 is a single-hole aluminum compression lug rated for conductors up to 250 kcmil and system voltages up to 35 kV. The lug features a tin-plated aluminum body that resists corrosion and promotes a low-resistance connection at the termination point. A 1/2-inch bolt hole accommodates standard bus bar and equipment terminal hardware. Electricians and utility technicians use this lug to terminate large aluminum feeders and service conductors on switchgear, transformers, and distribution equipment. The red die color code streamlines field identification during compression installation.

This lug is suited for medium-voltage and low-voltage termination work in commercial, industrial, and utility applications. It is used wherever large aluminum conductors must be terminated to bolted bus or equipment studs, including switchgear lineups, transformer secondary terminations, and service entrance equipment. The 35 kV rating makes it appropriate for both distribution-class and utilization-voltage installations.

Key Features

• Aluminum body with tin plating for corrosion resistance and reliable contact
• Rated for wire sizes up to 250 kcmil aluminum conductor
• Maximum system voltage rating of 35 kV
• 1/2-inch bolt hole for compatibility with standard terminal hardware
• Single-hole mounting configuration for compact termination points
• Red die color code for quick identification during compression operations

Compatibility

Designed as an OEM-style compression termination lug for aluminum conductors up to 250 kcmil in medium-voltage and low-voltage electrical assemblies where a one-hole bolted termination is required.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for conductor terminations. De-energize and lock out the circuit before beginning any termination work. Use a calibrated compression tool with the correct die set matched to the red die color code to achieve a proper crimp. Inspect the compressed barrel for cracks or deformation before torquing the mounting bolt to the equipment terminal specification.
