Product FAQs
5 answersWhich panelboards are compatible with the TK236125 breaker?
This bolt-on breaker is designed for use in GE A-Series panelboards, as well as compatible GE switchboards and motor control centers.
How does the trip unit function on the TK236125?
It features a thermal magnetic trip unit with fixed thermal protection for overloads and an adjustable magnetic setting for instantaneous short-circuit protection. This allows electricians to coordinate the instantaneous trip point with other devices in the system.
What type of wiring is accepted by the standard lugs on this breaker?
The factory lugs accept both copper and aluminum conductors ranging from 4 AWG to 300 kcmil. Ensure proper torque specifications are followed during installation as outlined by the manufacturer.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this K-frame breaker may carry either the GE or ABB brand name, but the physical dimensions and performance specifications remain identical.
Does this breaker require a specific mounting hardware kit?
As a bolt-on MCCB, it mounts directly to the bus in compatible GE A-Series panelboards and switchboards. Verify if your specific enclosure requires a separate mounting kit or filler plates for K-frame breakers.
