Description
Part of the GE MeterMod family, the TMQD32175 is a 3-pole, 175A MCCB for commercial power distribution. It provides thermal-magnetic protection with fixed LI trip functions. This bolt-on breaker mounts into GE Meter Mod III stacks and A-Series panelboards. It serves as a predecessor to the TMQV32175 frame for legacy maintenance. Rated for 100kA at 240VAC, it safely clears severe fault currents. The unit is HACR rated and features non-interchangeable trip units.Specifications

Product FAQs
8 answersWhat equipment is the TMQD32175 designed to be installed in?
This breaker bolts directly into GE Meter Mod III modular metering stacks and GE A-Series panelboards.
Is the TMQD32175 interchangeable with the TMQV32175?
Yes. The TMQV32175 is the direct, official replacement frame for the legacy TMQD32175. Both share the same form factor, fit, and function for GE Meter Mod III and A-Series panelboards.
What is the difference between GE and ABB branding for the TMQD32175?
Following ABB's acquisition of GE Industrial Solutions, this breaker may be labeled as either ABB or GE depending on the production date. The physical breaker, specifications, and compatibility remain identical regardless of the brand printed on the label.
How does the TMQD frame differ from TQD or THQD breakers?
While they share similar dimensions, the primary difference is the interrupting capacity (AIC). TQD breakers are rated for 10kAIC, THQD for 22kAIC, and TMQD for 100kAIC at 240V. TMQD breakers are specifically designed for high fault current applications like Meter Mod III stacks.
What does the LI trip function code indicate on this breaker?
The LI designation means the breaker is equipped with a thermal-magnetic trip unit providing Long-Time (thermal) protection against overloads and Instantaneous (magnetic) protection against short circuits.
Can the trip settings on the TMQD32175 be adjusted in the field?
No. This breaker features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings. It cannot be adjusted or swapped for a different trip unit in the field.
Can the TMQD32175 be reverse fed?
Yes, TMQD frame circuit breakers are designed with reverse feed capabilities, allowing them to be back-fed in compatible panelboard and metering applications.
Is the TMQD32175 HACR rated?
Yes, this breaker carries an HACR rating, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.
