Product FAQs
5 answersWhich metering equipment is the TMQC22175MM compatible with?
This breaker is specifically designed for use with GE Meter Mod III Modular Metering Stacks. It typically serves as a tenant main breaker within these modular enclosures.
What are the acceptable wire sizes and materials for the terminal lugs?
The factory-installed lugs accept wire gauges from 6 AWG up to 4/0 AWG. They are dual-rated for both copper and aluminum conductors.
Is the TMQC22175MM suitable for high fault current applications?
Yes, it features a 42kAIC interrupting rating at 240VAC. This high interrupting capacity makes it appropriate for commercial or multi-family metering centers where available fault currents exceed standard 10kAIC or 22kAIC levels.
How does the TMQC22175MM connect to the metering stack bus?
It utilizes a bolt-on connection to secure directly to the buswork of the Meter Mod III stacks. This ensures a reliable mechanical and electrical connection for high-amperage tenant feeds.
Does this breaker offer adjustable trip settings?
No, the thermal magnetic trip unit features fixed long-time and fixed instantaneous trip functions. It does not have adjustable dials to modify the trip curve.
