Designed for advanced commercial power systems, the ABB XT1HU3060AYD000XXX is a 3-pole, 60A molded case circuit breaker from the SACE Tmax XT1 family. It provides robust protection via a fixed thermal-magnetic trip unit. This unit-mount MCCB features a ReliaGear plug-in connection and load-side lugs, streamlining installation into ABB ReliaGear NeXT panelboards. It upgrades legacy Tmax T1 series breakers. Rated for 65kAIC at 480V, this current-limiting breaker is HACR rated.
What type of panelboard is this Tmax XT1 breaker designed for?
It is engineered for use with ABB ReliaGear NeXT power panelboards, integrating seamlessly into their distribution architecture.
Does this breaker plug onto the busbar or use a separate mounting method?
It is a unit-mount circuit breaker. Instead of plugging directly onto the bus, it requires mechanical fasteners to secure it to the backpan or chassis before landing the line and load conductors.
Are the overcurrent protection settings adjustable on this model?
No. It is equipped with a thermal-magnetic trip unit that has fixed long-time and fixed instantaneous settings. Field adjustments to the trip curve are not supported on this specific configuration.
What conductor sizes are supported by the factory terminals?
The included lugs accept wire sizes ranging from 10 AWG up to 2/0 AWG. Always verify and apply the proper torque values labeled on the breaker during installation to ensure a secure connection.
