Delivering robust overcurrent protection, the GE TMQD22150 is a 150A, 2-pole molded case circuit breaker. It utilizes fixed thermal-magnetic trip technology to safeguard 120/240VAC circuits. The unit is engineered to bolt into GE Meter Mod III meter stacks and A-Series panelboards. While it remains crucial for legacy maintenance, GE designates the TMQV22150 as its replacement.Specifications

Product FAQs
6 answersWhich panelboards and meter stacks are compatible with the TMQD22150?
This bolt-on breaker is specifically designed for installation in GE A-Series panelboards and GE Meter Mod III meter stacks.
Can I install this breaker in a standard GE Powermark Gold load center?
No. The TMQD22150 is a bolt-on molded case circuit breaker. It will not fit in residential plug-on load centers like the Powermark Gold series, which typically require THQL or THHQL plug-in breakers.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, the TMQD22150 may feature either ABB or GE branding. Regardless of the label, the physical dimensions, mounting hardware, and UL listings are identical.
What wire sizes and materials are supported by the factory lugs?
The included lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 1 AWG to 300 kcmil. Always verify the required torque specifications printed on the breaker label before terminating the wires.
Are the trip settings on the TMQD22150 adjustable?
No. This breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory set and cannot be adjusted in the field.
What does the 100kAIC rating indicate for this breaker?
The 100kAIC rating means the breaker can safely interrupt up to 100,000 amps of fault current at 240VAC without sustaining catastrophic damage. This high interrupting capacity is typically required in commercial or industrial facilities with high available fault currents.
