Product FAQs
6 answersWhat frame size does the THLC236175 belong to?
The THLC236175 is part of the GE THLC2 frame family, which encompasses current-limiting molded case circuit breakers ranging from 125A to 225A.
What does the WL suffix mean if I see this breaker listed as THLC236175WL?
The WL suffix in the GE catalog number indicates that the circuit breaker is supplied with factory-installed line and load lugs.
How does the current-limiting design of the THLC236175 protect downstream equipment?
Current-limiting breakers are engineered to clear severe short circuits extremely fast, typically within a half-cycle. This significantly reduces the peak let-through current and energy, minimizing thermal and mechanical stress on downstream electrical components.
Can the THLC236175 be installed in a standard residential load center?
No, the THLC236175 is a heavy-duty, bolt-on molded case circuit breaker designed specifically for commercial and industrial GE switchboards and motor control centers. It is not compatible with standard residential plug-on panels.
Are the trip units on the THLC236175 interchangeable?
No, the THLC236175 features a non-interchangeable thermal-magnetic trip unit. The long-time and instantaneous trip settings are fixed at the factory and cannot be modified or swapped in the field.
Is the GE THLC236175 considered a legacy circuit breaker?
Yes, the THLC236175 is a legacy GE circuit breaker. It is typically sourced to maintain, repair, or expand existing industrial GE switchboards and motor control centers rather than for new system designs.
