The ABB OZXA-26 is a terminal lug kit — six lugs rated for wire sizes from #2 AWG to 600 MCM, accepting both copper and aluminum conductors. It is designed specifically for the OES400 and OETL-NF400 series fusible and non-fusible flange operated disconnect switches.
The #2-600 MCM wire range covers most service-entrance and feeder conductors for 400 A class disconnects. The Cu/Al rating means no separate lug kit is needed when switching between copper and aluminum — just torque to the manufacturer's spec for each material. Six lugs in the kit handle a three-phase line plus neutral and ground, or a six-wire feeder configuration.
This kit mounts directly to the line and load terminals of OES400 and OETL-NF400 flange operated disconnect switches — the type found in industrial control panels, machine disconnects, and motor control centers where a padlockable, visible-break switch is required by code.
