Product FAQs
8 answersWhat does the "WL" suffix mean in the THKMA836500WL catalog number?
The "WL" suffix indicates that the breaker ships from the factory with line and load lugs included, so a separate lug kit is not required for installation.
What wire sizes are accepted by the terminals on the THKMA836500WL?
The included factory lugs accept up to three copper or aluminum conductors per phase, ranging from 3/0 AWG to 500 kcmil.
Is the trip unit on the THKMA836500WL adjustable?
Yes, this thermal magnetic breaker features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
What types of equipment can the THKMA836500WL be installed in?
This legacy K-Frame breaker is designed for use in GE A-Series panelboards, switchboards, and motor control centers.
Can the THKMA836500WL replace older TKMA breakers?
Yes, the THKMA836500WL is a direct replacement for older TKMA836500 models within the GE legacy K-Frame series.
What are the modern retrofit options for the THKMA836500WL?
For modern upgrades, this legacy K-Frame breaker can be replaced by GE Spectra RMS SKHA36AT0500 or ABB Tmax XT5 models using the appropriate retrofit kits.
How is the THKMA836500WL mounted?
This is a unit mount breaker with a feed-thru connection type, meaning it is typically bolted directly to the mounting surface or enclosure rather than plugging into a busbar.
What type of protection does the LI trip function provide?
The LI designation means the breaker includes Long-Time and Instantaneous trip functions, providing safety against both sustained overloads and sudden short circuits.
