Product FAQs
5 answersWhich panelboards and meter stacks are compatible with the TMQD32125 breaker?
This bolt-on breaker is designed for direct installation in GE A-Series panelboards and GE Meter Mod III meter stacks.
What wire sizes are accepted by the terminals on the TMQD32125?
The factory-installed lugs accept wire gauges from 1 AWG up to 300 kcmil. They are rated for use with both copper (Cu) and aluminum (Al) conductors.
Will the TMQD32125 arrive with ABB or General Electric branding?
Because ABB acquired GE Industrial Solutions, this breaker may feature either ABB or GE branding. The physical dimensions, mounting hardware, and performance specifications remain identical regardless of the label.
What applications require the 100kAIC rating of the TMQD frame?
The 100kA interrupting capacity at 240V makes this breaker suitable for commercial and industrial electrical systems where available fault currents exceed standard 10kAIC or 65kAIC levels, providing enhanced safety during severe short circuits.
How does the thermal magnetic trip unit operate on this breaker?
It features fixed Long-Time (L) and Instantaneous (I) protection. The thermal element provides delayed tripping for mild overloads, while the magnetic element trips instantly to clear severe short circuits.
