Product FAQs
6 answersWhat does the current limiting feature of the THLC136020WL do?
As a current limiting breaker, it restricts the let-through energy during a fault. This protects sensitive downstream equipment from excessive thermal and magnetic stress by clearing the fault faster than standard breakers.
Where can I install the THLC136020WL circuit breaker?
This unit mount breaker is designed for use in GE switchboards, motor control centers, and individual enclosures. It is a feed-thru style breaker and is not designed to plug into standard load centers.
Does the THLC136020WL require a specific mounting hardware kit?
Yes, when installing this THLC1 frame breaker in a Spectra series panelboard, you will need a compatible mounting hardware kit, such as the AHKBE1.
Which auxiliary switches are compatible with the THLC136020WL?
You must use accessories designed for GE THLC1 frame molded case circuit breakers. For example, the TEDAS2AB1R auxiliary switch is compatible with this frame.
How does the THLC136020WL connect to the power source?
It features a feed-thru, unit mount design. This means it bolts directly to the mounting surface or enclosure backpan and uses wire lugs for both line and load connections, rather than plugging onto a busbar.
Can I adjust the trip settings on the THLC136020WL?
No. It features a fixed thermal and fixed magnetic trip unit. This provides both long-time overload protection and instantaneous short-circuit protection, but the trip points cannot be adjusted in the field.
