Overview

The ABB WR359 is an aluminum wide range H-type compression connector designed for overhead power distribution systems. This connector accommodates a main conductor range of 4/0 to 3/0 AWG ACSR and a tap conductor range of 4 to 6 AWG ACSR, 3 to 6 AWG stranded, or 2 to 6 AWG solid. The WR359 uses die size D and D3, ensuring compatibility with standard compression tooling. With a length of 1-7/8 inches, this connector provides a secure mechanical and electrical connection for branch circuits in utility and industrial applications. The aluminum construction offers corrosion resistance and lightweight durability compared to copper alternatives. Installation requires a hydraulic or mechanical compression tool rated for the specified conductor ranges. Typical applications include overhead line taps, service drops, and secondary distribution systems where reliable conductor splicing is critical. The WR359 is part of ABB’s Installation Products line, known for compliance with utility-grade standards for mechanical strength and electrical conductivity. Always verify conductor compatibility and tooling requirements before installation.
