Product FAQs
5 answersWhich panelboards and enclosures are compatible with the TKMA836700 breaker?
This K-frame breaker is designed for use in legacy GE switchboards, motor control centers, and GE CCB or AV1 series panelboards.
What are the acceptable wire sizes for the lugs on this breaker?
The standard lugs accept three conductors per phase, ranging from 3/0 AWG to 500 kcmil for both aluminum and copper wire.
How does the trip unit function on the TKMA836700?
It features 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.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Legacy GE breakers like the TKMA series are now managed under the ABB brand portfolio, though they retain their original GE catalog numbers and physical form factors.
Does the TKMA836700 require a specific mounting hardware kit?
As a bolt-on MCCB, it requires the appropriate strap kits or mounting hardware specific to the GE CCB or AV1 panelboard interior it is being installed into. Hardware kits are typically sourced separately based on the exact enclosure.
