Description
Built for heavy-duty industrial applications, the GE TKMA836500WL is a 3-pole, 500A MCCB from the K1200 line. It delivers reliable power distribution at up to 600VAC. This unit-mount breaker fits feed-thru configurations in GE switchboards and motor control centers. It can be replaced by the modern Tmax XT5 series using a retrofit kit. The "WL" suffix signifies that line and load lugs are included.Specifications

Product FAQs
8 answersWhat does the "WL" suffix indicate on the TKMA836500WL catalog number?
The "WL" suffix indicates that the circuit breaker is supplied from the factory with both line and load lugs included. If ordered without this suffix, the breaker frame is supplied without lugs.
What is the difference between the TKMA836500WL and the THKMA836500WL?
Both are 500A, 3-pole K-Frame circuit breakers, but the THKMA series features a higher short-circuit interrupting rating (AIC) than the standard TKMA series. They share the same physical footprint and mounting requirements.
Does the TKMA836500WL feature an interchangeable trip unit?
Yes, this breaker is part of the GE K1200 line and features an interchangeable thermal-magnetic trip unit. This allows the trip unit to be swapped or replaced without removing the entire breaker frame from the panel.
How does the trip unit on the TKMA836500WL operate?
It utilizes a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Which GE panels and switchboards are compatible with the TKMA836500WL?
This unit-mount K-Frame breaker is designed for installation in GE switchboards, motor control centers, GE CCB panelboards, and GE AV1 panelboards.
What wire sizes are accepted by the lugs on the TKMA836500WL?
The factory-installed lugs accept up to three conductors per phase, supporting 3/0 AWG to 500 kcmil aluminum or copper (Al/Cu) wire.
Is there a modern replacement for the legacy GE TKMA836500WL?
Yes, since the GE K-Frame is a legacy product, it can be upgraded or replaced using the modern ABB Tmax XT5 series circuit breakers along with the appropriate retrofit kit.
What does a feed-thru connection mean for this breaker?
A feed-thru connection means the breaker is designed to be hardwired on both the line and load sides using the provided lugs, rather than plugging directly into a busbar system.
