Single-Pole 400 A Inline Connector

The Hubbell HBL400FR is a female single-pole inline connector rated for 400 A at 600V AC or 250V DC. It accepts cable sizes from 2/0 to 4/0 AWG using a double set screw terminal. The red thermoplastic elastomer housing and brass contacts suit temporary power distribution in demanding environments.

Series 16 Compatibility Upgrade

This connector replaces worn or mismatched Series 16 cam devices where a secure female taper-nose fitting is required. The jump is worth it when existing terminals show heat damage or when a NEMA 3R, 4X or 12 enclosure rating is needed for outdoor or wash-down service.

Double Set Screw Installation

Installation uses the integrated double set screw terminals; no specialised crimp tool is required for the 2/0 to 4/0 AWG range. Common issues include under-torqued screws causing voltage drop and debris in the taper-nose interface preventing full mating with the male counterpart.
