Product FAQs
6 answersWhat equipment is the TF136020 circuit breaker designed to be installed in?
This bolt-on molded case circuit breaker is compatible with GE A-Series panelboards, switchboards, and motor control centers.
What wire size range do the lugs on the TF136020 accept?
The included lugs accept wire gauges from 14 AWG up to 1/0 AWG. Ensure you use the proper torque specifications listed on the breaker label during installation.
What does the LI trip function indicate on this GE TF frame breaker?
The LI designation means the breaker features a thermal magnetic trip unit with fixed Long-Time (thermal) and fixed Instantaneous (magnetic) protection. This provides standard overload and short circuit protection.
Can the TF136020 be used in DC electrical systems?
Yes, this breaker is rated for DC applications up to 250VDC, where it provides an interrupting capacity of 10kAIC.
Why is this breaker listed under the ABB / General Electric brand?
ABB acquired GE Industrial Solutions. Legacy GE molded case circuit breakers, including the TF frame series, are now manufactured and supported under the ABB brand umbrella.
Does the TF136020 require a specific mounting hardware kit?
As a bolt-on circuit breaker, it secures directly to the busbar using bolted connections. Depending on your specific A-Series panelboard or switchboard chassis, you may need a dedicated mounting kit or strap if one is not already present in the enclosure.
