Abb xt5hu360bbyn000xxx Circuit Breaker 600A 480V 3P

Product Description

The ABB xt5hu360bbyn000xxx is a 3-pole molded case circuit breaker from the Tmax XT Series, rated at 600 amps and 480 volts with a 65 kA interrupting capacity. It uses a TMA (thermal-magnetic adjustable) trip mechanism with a trip range of 600 to 6000 amps, allowing field adjustment to match the protected load. The breaker accepts copper or aluminum conductors from 2/0 AWG to 500 kcmil at both the line and load side lug terminals. Electricians and electrical contractors install this device in commercial and industrial distribution panels where high-capacity branch or feeder protection is required.

This breaker is specified as a Loadside Circuit Breaker (LSC) for use in the ReliaGear neXT Power Panelboard system. It is suited for three-phase commercial and industrial applications operating on 50 or 60 Hz systems at up to 480 volts. The fixed-frame (FF) configuration and compact footprint make it appropriate for installations where panel space is a limiting factor.
