Overview

The ABB HLC3974AP9-1 Hot Line Clamp is a robust electrical connector designed for reliable power distribution applications. Manufactured by ABB - Installation Products, this clamp is constructed from durable aluminum with a tin-plated finish for enhanced conductivity and corrosion resistance. It features Contax filling, which ensures a low-resistance connection and prevents oxidation, crucial for maintaining electrical integrity over time. The front tap design facilitates easy and secure conductor connections. This hot line clamp is engineered to accommodate a wide range of conductor sizes. The main conductor range supports stranded conductors from 400 KCMIL down to 6, and solid conductors from 185 sq mm down to 16 sq mm. For tap connections, it accepts stranded conductors from 4/0 down to 6, and solid conductors from 95 sq mm down to 16 sq mm. Specifically, it is rated for 397-5 to 6 ACSR main conductors and 3/0 to 6 ACSR tap conductors. The clamp utilizes a 9/16 nut for secure tightening. Key specifications include:
  • Durable aluminum construction with tin-plated finish for corrosion resistance.
  • Contax filling ensures low-resistance connections and prevents oxidation.
  • Front tap design for convenient conductor connection.
  • Accommodates main conductors from 400 KCMIL (stranded) and 185 sq mm (solid).
  • Supports tap conductors from 4/0 (stranded) and 95 sq mm (solid).
