Product FAQs
5 answersWhich panelboards are compatible with the TF126100 circuit breaker?
This F-frame breaker is designed for bolt-on installation in GE A-Series panelboards, Spectra Series switchboards, and compatible motor control centers. Always verify acceptance on the interior panel label before installation.
How is the TF126100 secured within the electrical enclosure?
It uses a bolt-on mounting configuration to attach directly to the line side bus. The load side is equipped with standard lugs accommodating 14 to 1/0 AWG conductors.
What protection does the LI trip function provide on this breaker?
The LI designation indicates a thermal-magnetic trip unit with fixed Long-Time and fixed Instantaneous functions. The thermal element protects against sustained overloads, while the magnetic element trips immediately during short-circuit events.
Why might this breaker have either ABB or GE branding?
ABB acquired GE Industrial Solutions, meaning legacy GE product lines like the TF series are now manufactured under the ABB name. Breakers with either label share the exact same specifications and are fully interchangeable in compatible equipment.
Can I install this GE F-frame breaker in a panelboard from another manufacturer?
No. To maintain UL compliance and ensure safe operation, this breaker must only be installed in GE or ABB enclosures that explicitly list the TF series or F-frame breakers on their compatibility label.
