Description
Built for standalone applications, this 200-amp current-limiting circuit breaker provides robust protection for industrial electrical systems. The unit-mount design includes factory-installed line and load lugs, allowing it to mount into individual enclosures, GE switchboards, and motor control centers. With a fixed thermal-magnetic trip, it achieves a 200kAIC rating at 480V, effectively restricting let-through current to shield downstream components.Specifications

Product FAQs
6 answersWhy is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the THLC236200WL may arrive with either GE or ABB branding, but the physical dimensions, UL listings, and performance ratings remain identical.
What does the WL suffix in the THLC236200WL part number indicate?
The WL suffix designates that the breaker comes factory-equipped with line and load lugs. These included lugs accept 4 AWG to 300 kcmil copper or aluminum conductors.
Where can the THLC236200WL be installed?
This unit mount breaker is designed for use in GE switchboards, motor control centers, and individual enclosures. It is a feed-thru breaker and does not plug onto a panelboard bus.
How does the current limiting feature of the THLC2 frame work?
Current limiting breakers like the THLC236200WL are designed to clear a fault in less than half a cycle. This rapid action significantly reduces the peak let-through current and let-through energy, protecting downstream equipment from severe electrical and mechanical stress during high fault conditions up to 200kAIC at 480V.
Can the trip settings on this 200A breaker be adjusted?
No. The THLC236200WL features a fixed thermal and fixed magnetic trip unit. Neither the long-time overload nor the instantaneous short-circuit pickup levels can be modified in the field.
Does the interrupting capacity change depending on the system voltage?
Yes. While the THLC236200WL provides a high interrupting capacity of 200kAIC at 240VAC and 480VAC, the rating drops to 50kAIC when applied to a 600VAC system. Always verify the available fault current at your specific installation voltage.
