Description
Built for heavy-duty applications, the GE TF126090 is a 2-pole, 90-amp molded case circuit breaker from the legacy F-Frame series. It delivers robust long-time and instantaneous trip functions for commercial and industrial facilities. This bolt-on unit installs into vintage GE A-Series panelboards, switchboards, and motor control centers. It serves as a direct cross-reference for TED126090 and THED126090 models. Operating at up to 600VAC, it features a non-interchangeable trip and 22 kAIC.Specifications

Product FAQs
7 answersWhich GE enclosures and panels are compatible with the TF126090?
The TF126090 is engineered for compatibility with GE A-Series panelboards. It is also suitable for integration into GE switchboards and motor control centers that accept legacy F-Frame breakers.
What are the wire size requirements for the load side terminals?
The breaker comes equipped with load side lugs that accept wire gauges from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Is the TF126090 suitable for direct current applications?
Yes, while primarily used in 600VAC systems, this breaker is also rated for 250VDC applications, where it provides a 10kA interrupting capacity.
Does the TF126090 offer adjustable trip settings?
No, this breaker is equipped with a non-interchangeable thermal-magnetic trip unit. Both the long-time and instantaneous (LI) trip functions are fixed and cannot be adjusted in the field.
What frame size is the TF126090?
This breaker belongs to the legacy GE F-Frame family of molded case circuit breakers.
How does the TF126090 connect to the panel bus?
This is a bolt-on circuit breaker. It requires mechanical fasteners to bolt directly onto the busbars of the panelboard, providing a secure and reliable connection for heavy-duty environments.
Why is the 22kAIC rating at 600VAC important for installation?
The 22kA Ampere Interrupting Capacity (AIC) indicates the maximum fault current the breaker can safely interrupt at 600VAC. Electricians must verify that this rating meets or exceeds the available fault current at the installation point to ensure safety and code compliance.
