Product FAQs
5 answersWhat equipment is the TMQL21125 circuit breaker designed to fit?
This breaker is specifically engineered as a tenant main breaker for GE Meter Mod III modular metering stacks. It features a plug-in mounting configuration designed exclusively for these meter modules.
Will I receive an ABB or GE branded TMQL21125 breaker?
You may receive either an ABB or GE branded unit. Following the acquisition of GE Industrial Solutions by ABB, these breakers are manufactured to the exact same form, fit, and function specifications. Only the branding label differs based on the production date.
Are the box lugs on the TMQL21125 rated for aluminum wiring?
Yes, the box lug terminals are rated for both copper and aluminum conductors, accepting wire sizes from 2 AWG up to 2/0 AWG.
Is the TMQL21125 interchangeable with standard THQL breakers?
While the TMQL21125 shares the same physical frame size as the THQL series, it is specifically configured as a plug-in tenant main breaker for GE Meter Mod III metering stacks. It should not be used as a direct substitute for standard THQL branch breakers in residential load centers.
What type of protection does the LI trip function provide on this breaker?
The fixed thermal-magnetic trip unit provides Long-Time (L) protection for overloads and Instantaneous (I) protection for short circuits.
