Product FAQs
9 answersWhat panelboards is the XT1HU3125AYD000XXX compatible with?
This 3-pole molded case circuit breaker is engineered specifically for ABB ReliaGear neXT panelboards and ReliaGear SB switchboards.
How does the YD suffix affect the installation of this breaker?
The YD suffix indicates that the breaker features a specialized plug-in line connection designed for ReliaGear bus stacks. This allows for a much faster and simpler installation process compared to traditional bolt-on breakers.
What is the alternate catalog description for the XT1HU3125AYD000XXX?
This breaker is frequently listed under the alternate designation RGXT1H 125 TMF 125-1250 3P. The RG prefix stands for ReliaGear, while 125-1250 indicates the 125A fixed thermal setting and the 1250A instantaneous magnetic trip threshold.
Are the thermal and magnetic trip settings on this breaker adjustable?
No, it is equipped with a Thermal Magnetic Fixed (TMF) trip unit. Both the long-time (overload) and instantaneous (short-circuit) protection limits are factory-set and cannot be adjusted by the user.
Can the XT1HU3125AYD000XXX be used in high-fault 480V environments?
Yes, the H in the XT1H frame designates a high interrupting capacity. It provides a robust 65 kA short-circuit rating at 480 VAC, making it suitable for demanding industrial and commercial distribution applications.
What type of conductors can be landed on the breaker's terminals?
The standard load lugs accept either copper (Cu) or aluminum (Al) wire, accommodating conductor sizes between 10 AWG and 2/0 AWG.
What older ABB circuit breaker series does the Tmax XT1 replace?
The SACE Tmax XT1 frame is the direct upgrade for the legacy ABB Tmax T1 series, offering improved short-circuit protection and integration within a similarly compact footprint.
Is the XT1HU3125AYD000XXX rated for DC power systems?
Yes, this XT1 frame breaker is certified for use in direct current applications. It provides a 50 kA interrupting capacity at 250 VDC.
How does the fixed thermal-magnetic trip unit protect industrial equipment?
The thermal element utilizes a bimetallic strip that bends and trips the breaker during sustained overloads to prevent overheating. The magnetic element detects massive current spikes from short circuits and trips instantaneously, minimizing potential damage to the panelboard and connected load.
