Product FAQs
5 answersWhich panelboards and enclosures are compatible with the THLC136080?
This bolt-on circuit breaker is designed for use in GE A-Series panelboards, GE Spectra panelboards, switchboards, and motor control centers. Verify specific enclosure compatibility and busbar configurations before installation.
How does the current limiting feature of this breaker benefit the electrical system?
As a current limiting breaker, it is designed to clear short circuits in less than a half-cycle. This significantly reduces the peak let-through current and energy, providing enhanced protection for downstream components and allowing for its high 200kAIC rating at 480VAC.
What are the wire size requirements for the terminal lugs on this breaker?
The factory-installed lugs accept 6 AWG to 1/0 AWG copper wire, or 4 AWG to 1/0 AWG aluminum wire. Ensure conductors are properly torqued according to the label on the breaker to maintain a secure and compliant connection.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the exact date of manufacture, the THLC136080 may feature either GE or ABB branding, but the physical dimensions, ratings, and UL listings remain identical.
What type of trip unit is installed in the THLC136080?
It features a non-interchangeable thermal magnetic trip unit with fixed long-time and instantaneous (LI) functions. This provides standard overload protection (thermal) and immediate short-circuit protection (magnetic) without requiring field adjustments.
