Product FAQs
6 answersWhat wire size do the included lugs on the THKMA31000WL accept?
The factory-installed lugs accept up to four 250 to 500 kcmil copper or aluminum conductors per phase. Ensure proper torque specifications are followed during installation.
What types of enclosures or panels is this K-frame breaker compatible with?
This unit-mount breaker is designed for installation in GE switchboards, motor control centers, and GE A-Series panelboards.
How is the trip unit configured on the THKMA31000WL?
