Product FAQs
7 answersWhat equipment is the TMQV22125MM designed to be installed in?
This breaker is specifically designed for use in GE Meter Mod III and Mini Mod III meter stacks, where it functions as a tenant main breaker.
Can the TMQV22125MM replace older TMQD series breakers?
Yes, the TMQV22125MM serves as a direct drop-in replacement for the legacy TMQD22125. It maintains the same physical footprint for existing 125A sockets while offering an upgraded 100kAIC interrupting rating.
Why might this breaker arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. As a result, TMQV series breakers may feature either ABB or GE branding depending on the production batch, but the form, fit, and function remain identical.
Does the TMQV22125MM come with load lugs installed?
Yes, this breaker includes factory-installed load lugs that accept #4 AWG to 4/0 AWG copper or aluminum wire, as well as the necessary mounting hardware for bolt-on installation in meter stacks.
What does the "MM" suffix in the TMQV22125MM catalog number indicate?
The "MM" suffix indicates that the breaker is configured with the necessary mounting hardware and load lugs specifically for GE Meter Mod III and Mini Mod III modular metering applications.
Why is a 100kAIC rating important for this tenant main breaker?
The extra-high 100kAIC interrupting capacity allows this breaker to safely clear severe fault currents often found in large multi-family or commercial group metering installations, ensuring superior protection compared to standard residential breakers.
Are the trip settings adjustable on the TMQV22125MM?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous trip functions.
