Abb xt7hu312epyw000xxr 1200A 480V 3-pole Mccb

Product Description

The ABB xt7hu312epyw000xxr is a 1200-amp, 480-volt molded case circuit breaker (MCCB) from the Tmax XT Series, designed for high-demand power distribution applications. It features a 3-pole configuration with an Ekip Touch LSI (Long-time, Short-time, Instantaneous) electronic trip unit, delivering precise and adjustable overcurrent protection. Rated for a 65 kA interrupting capacity, this breaker handles fault currents common in heavy commercial and industrial distribution systems. Copper and aluminum line and load lug connections accept wire sizes from 4/0 AWG to 500 kcmil, giving installers flexibility with conductor sizing. Licensed electricians and industrial controls technicians are the typical installers for this class of equipment.

This circuit breaker is rated for 50/60 Hz operation at 480 volts, making it suitable for three-phase commercial and industrial power distribution panels. It is listed as an LSC (Lug Set Compatible) device for the ReliaGear neXT Power Panelboard, making it a direct-fit option for that switchgear platform. Line and load side lug terminals are factory-installed, supporting straightforward field wiring on both the supply and load conductors. Typical installations include main and feeder breaker positions in industrial facilities, commercial buildings, and data center power distribution infrastructure.

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 panelboard or switchgear before beginning any installation or wiring work. Verify that conductor sizing falls within the listed range of 4/0 AWG to 500 kcmil and that lug torque is applied per the torque values printed on the breaker label or installation sheet provided with the unit. The Ekip Touch trip unit may require parameter configuration at commissioning — consult the manufacturer documentation before energizing.
