Product FAQs
8 answersWhat panelboards are compatible with the THEF134100 circuit breaker?
This E-Frame bolt-on breaker is designed for installation in GE A-Series panelboards, GE switchboards, and compatible motor control centers.
Can the THEF134100 be used as a replacement for other GE E-150 line breakers?
Yes, it shares the same physical dimensions and bolt-on mounting footprint as other E-150 line breakers, such as the THED134100 and TED134100. You must verify that the 25kAIC at 480VAC interrupting rating meets or exceeds your specific system requirements before substituting.
Is this breaker suitable for direct current applications?
Yes, the thermal magnetic trip unit is rated for DC use. It provides an interrupting capacity of 10kA at 250VDC.
What wire sizes and materials do the factory lugs accept?
The standard lugs are rated for both copper and aluminum conductors. They accommodate 3 AWG to 3/0 AWG copper wire, or 1 AWG to 3/0 AWG aluminum wire.
What protection does the LI trip function provide on this breaker?
The LI designation indicates a thermal magnetic trip unit equipped with fixed Long-Time thermal protection for sustained overloads and fixed Instantaneous magnetic protection for short circuits.
Why might this GE breaker arrive with ABB branding?
ABB acquired GE Industrial Solutions in 2018. Depending on the production batch, E-Frame breakers may feature either ABB or GE branding. The physical dimensions, mounting, and electrical specifications remain identical regardless of the label.
How is the THEF134100 secured inside the enclosure?
It features a bolt-on connection type. The breaker must be mechanically fastened directly to the busbars using the appropriate mounting hardware within a compatible GE A-Series panelboard or switchboard.
What frame family does the THEF134100 belong to?
It is part of the GE E-150 line of E-Frame molded case circuit breakers. These compact breakers are widely utilized in commercial and industrial power distribution systems.
