Overview

The ABB 4NPW Service Entrance Connector (SKU: 4NPW) is a specialized electrical component designed for secure and reliable connections in service entrance applications. Manufactured by ABB - Installation Products, this connector is engineered from copper for optimal conductivity and durability. Its tin plating offers significant resistance to corrosion, ensuring long-term performance even in challenging environmental conditions. The connector is specifically designed to accommodate a wire range of ACSR (Aluminum Conductor Steel Reinforced) from sizes 6 to 8, and copper conductors ranging from 6 solid to 4 stranded. A key feature of the 4NPW is its integrated tin-plated phosphor bronze washer. This washer plays a crucial role in protecting the conductor from damage during installation and tightening. It also serves to evenly distribute the pressure applied by the connector, preventing conductor deformation and ensuring a consistent, low-resistance electrical path. This design detail is vital for maintaining the integrity of the connection and preventing potential failures over time.
  • Copper construction for excellent conductivity
  • Tin plating resists corrosion for durability
  • Accommodates ACSR wire range 6 to 8
  • Accepts Copper wire range 6 Solid to 4 Stranded
  • Phosphor bronze washer protects conductor and distributes pressure
