Circuit Breaker · 80A 2-Pole 120/240V · Bolt-On Thermal-Magnetic · ABB THQB2180
What this product is for
The ABB THQB2180 is a Q-Line miniature circuit breaker for branch circuit protection where an 80A, 2-pole, 120/240V AC bolt-on breaker is required. It is used to provide overload and short-circuit protection in compatible load centres, lighting panels, and panelboards.
Use for
Use for 120/240V AC branch circuits in compatible ABB or legacy GE Q-Line panelboards and load centres that require a bolt-on mounting style. Typical applications include larger single-phase loads, subfeeds, HVAC equipment, and commercial distribution circuits where an 80A 2-pole breaker is specified.
Avoid for
Avoid using this breaker where a plug-in style breaker is required, where interrupting capacity above 10 kA is needed, or where the panelboard label does not list THQB series breakers as approved. Do not substitute based on appearance alone; breaker series and panel compatibility must match the equipment labelling and local code requirements.
Best for
Best for electricians replacing or specifying an ABB/GE Q-Line bolt-on breaker in existing commercial panels or load centres. It is a practical choice when the job calls for the THQB footprint, 2-pole common trip protection, and standard 10 kAIC performance at 120/240V AC.
Installed in
Installed in compatible ABB and legacy GE Q-Line lighting panels, load centres, and panelboards using bolt-on bus connections. As a rule of thumb, an 80A breaker is typically paired with conductors and equipment sized by the engineer, panel rating, terminal range, and applicable Canadian Electrical Code requirements.
Why this product exists
This breaker exists for applications where a secure bolt-on connection is preferred or required in panelboards and lighting panels. Compared with plug-in styles, bolt-on breakers are commonly selected in commercial distribution equipment to help maintain secure mounting and consistent contact at the bus connection.
Compared with similar products
Compared with ABB/GE THQL breakers, the THQB2180 is the bolt-on version rather than plug-in. Compared with THHQB versions, this model carries a 10 kA interrupting rating instead of the higher interrupting rating offered by THHQB equivalents. Always confirm the exact breaker family listed on the panel schedule or equipment label before ordering.
