Product FAQs
6 answersWhat type of enclosures accept the THJK626600WL breaker?
This J-frame breaker installs directly into GE J600 series enclosures, as well as compatible commercial switchboards and motor control centers.
What wire sizes are supported by the factory lugs?
The included standard lugs accommodate dual runs of 4/0 AWG to 350 kcmil copper wire, or dual runs of 300 to 500 kcmil aluminum wire per phase.
Which trip elements are adjustable on this model?
The thermal magnetic trip unit features an adjustable magnetic trip dial for customizing instantaneous short circuit protection. The long-time thermal overload setting remains fixed at the rated capacity.
What does the WL suffix represent in the THJK626600WL part number?
The WL suffix indicates that the breaker is supplied with mechanical line and load lugs factory-installed. Breakers ordered without this suffix typically require separate lug kits.
Are there specific mounting requirements for this feed-thru breaker?
As a unit mount design, it bolts directly to the equipment backpan or mounting plate using standard hardware, rather than utilizing a plug-in or drawout base assembly.
Is this GE J-frame breaker suitable for direct current applications?
Yes, it is rated for DC distribution systems up to 250VDC, providing a dedicated interrupting capacity of 40kA for direct current faults.
