Abb k6tj Molded Case Circuit Breaker 800A T6 Tmax

Product Description

The ABB k6tj is a molded case circuit breaker terminal lug kit rated for 800 amps, designed to provide a secure standard cable termination point on T6 Tmax series molded case circuit breakers. This component allows field wiring connections using conductors ranging from 2/0 AWG through 400 MCM and accepts both aluminum and copper conductors, making it adaptable to a wide range of commercial and industrial wiring configurations. Electricians and electrical contractors install this terminal assembly during breaker commissioning or when upgrading existing switchgear and panelboard installations requiring high-ampacity connections.

This terminal kit is intended for use with ABB T6 Tmax series molded case circuit breakers in commercial and industrial power distribution applications. Typical installations include main distribution panels, motor control centers, and large commercial switchgear assemblies where 800-amp service capacity is required. The aluminum and copper conductor compatibility supports flexibility in feeder wiring design without requiring dedicated lug sets for each conductor material.

• Accepts conductors from 2/0 AWG to 400 MCM for wide wiring range coverage
• Compatible with both aluminum and copper conductors, reducing material constraints
• Standard cable terminal design for straightforward field installation on T6 Tmax breakers
• Molded case breaker accessory providing a factory-style termination interface

Compatibility

Designed for use with ABB T6 Tmax series molded case circuit breakers as specified in the product documentation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit breaker and associated upstream disconnect before beginning any terminal work. Use appropriately rated torque tools to tighten lug connections per the breaker manufacturer specifications; do not over-tighten aluminum conductors, as they are subject to creep deformation. Apply anti-oxidant compound to aluminum conductors before termination where required by the conductor manufacturer or local code.
