Description
Built for high-demand electrical distribution, the GE TMQD22125 is a 125A, 2-pole molded case circuit breaker. It delivers consistent thermal-magnetic protection for 120/240VAC systems. This breaker mounts into GE Meter Mod III meter stacks and A-Series panelboards using a secure bolt-on connection. It is frequently used to maintain existing infrastructure, replaced by the TMQV22125 in newer designs.Specifications

Product FAQs
6 answersWhat is the difference between TMQD and THQD circuit breakers?
The primary difference is the short-circuit interrupting rating. The TMQD series delivers an extra-high interrupting capacity of 100kAIC at 240VAC, whereas the standard THQD series is rated for 22kAIC. Both share the same physical footprint and bolt-on connection, allowing the TMQD to be used where higher fault current protection is required.
Where is the TMQD22125 breaker typically installed?
This 125A bolt-on breaker is designed for integration into GE Meter Mod III modular metering stacks, where it frequently serves as a tenant main breaker. It is also fully compatible with GE A-Series panelboards for standard branch or main circuit protection.
Will the TMQD22125 arrive with ABB or GE branding?
Because ABB acquired GE Industrial Solutions, this breaker may feature either ABB or General Electric branding depending on the production batch. The internal components, physical dimensions, and UL listings remain identical and fully interchangeable regardless of the logo on the label.
Do I need to purchase a separate lug kit for the TMQD22125?
No, this breaker comes equipped with factory-installed line and load lugs. The terminals are rated to accept either copper or aluminum conductors ranging from 6 AWG to 1/0 AWG.
Are the trip settings adjustable on the TMQD22125?
No, this is a fixed thermal-magnetic circuit breaker. The LI trip function code indicates it provides standard Long-Time overload and Instantaneous short-circuit protection, but neither threshold can be field-adjusted.
Can the TMQD22125 replace older TQD or THQD breakers?
Yes, the TMQD, THQD, and TQD series all share the same molded case frame size and bolt-on mounting configuration. You can install a TMQD22125 in a space previously occupied by a TQD22125 or THQD22125, provided the panel or meter stack is rated to accept a 100kAIC breaker.
