Abb xt1hu3100ayd000xxx 100A 3-pole Mccb

Product Description

The ABB xt1hu3100ayd000xxx is a 100-amp, 3-pole molded case circuit breaker (MCCB) built on the ABB XT1 frame platform. It uses a fixed thermal-magnetic trip unit rated for Long-Time and Instantaneous (LI) overcurrent protection, delivering interrupting capacities of 100 kA at 240 VAC and 65 kA at 480 VAC. The breaker ships with line side connectors and load side lugs already included, making it ready for immediate installation. Electricians and electrical contractors install this device in commercial and industrial power distribution applications where reliable, high-interrupting-capacity branch circuit protection is required.

The xt1hu3100ayd000xxx is rated for use in ABB ReliaGear neXT panelboards, ABB ReliaGear SB switchboards, and ABB SACE Tmax XT enclosures. It is unit-mount style and accepts wire gauge from 10 AWG to 2/0 AWG in copper or aluminum conductors. The breaker also serves as a direct substitute for the legacy T1H100TW, simplifying retrofit and upgrade projects in existing ABB distribution equipment.

Installation Notes

Installation must 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 panel or switchboard before installing or replacing the breaker. Verify wire gauge and conductor material are within the rated range of 10 AWG to 2/0 AWG copper or aluminum before terminating at the lugs. Optional accessories such as shunt trip or auxiliary switch must be installed per ABB installation instructions before the breaker is energized.
