Overview

The ABB WR875 is an aluminum wide-range H-type compression connector designed for reliable electrical connections in overhead distribution systems. This connector accommodates main conductors ranging from 477 to 556 kcmil (18/1-4/0 ACSR) and tap conductors from 336 to 397 kcmil (18/1-266 ACSR, 350-250 stranding). The 3-inch design ensures compatibility with standard utility hardware and provides a secure, low-resistance joint for long-term service. Manufactured by ABB Installation Products, the WR875 is optimized for ACSR conductors with 250-strand configurations, offering consistent performance in harsh outdoor environments. The compression design eliminates the need for multiple connector sizes, reducing inventory requirements while maintaining electrical integrity. Typical applications include utility pole connections, transformer taps, and branch circuits where reliable, maintenance-free joints are critical. The aluminum construction resists corrosion and provides excellent conductivity, ensuring stable performance over the connector's service life.
