Product details

3-pole MCCB for 3-phase distribution

The XT1HU3015AAA00NXXX: No field-adjustable trip settings; the protection profile is fixed at the factory.

For a panel builder or MRO planner, the XT1H 125 TMF frame is a standard catalog item; replacement units are orderable under the same MPN.

Panel fit and coordination

As a 3-pole MCCB on the 125 A frame, this breaker occupies a standard mounting footprint in ABB's XT1 molded case line. The fixed thermal-magnetic trip means no adjustment knobs on the front face — the trip curve is set at the factory, which simplifies coordination studies for the specifying engineer. For a commissioning engineer, the fixed-trip design eliminates the risk of field mis-adjustment. The breaker ships with the trip unit calibrated; install, torque the line and load lugs to the values on the label, and close the cover.

Frequently asked questions

What does the 3-pole configuration mean for this MCCB?

Three poles means the breaker simultaneously switches all three phases of a 3-phase circuit. This is the standard configuration for 3-phase feeder protection, motor branch circuits, and panelboard mains in North American and IEC distribution systems.

What is the XT1H 125 TMF trip unit?

The TMF trip unit is a thermal-magnetic fixed design on a 125 A frame. The thermal element provides inverse-time overload protection; the magnetic element provides instantaneous short-circuit protection. Trip settings are factory-fixed and not field-adjustable.
