Circuit Breaker · 2-Pole 100A 120/240V · Plug-In Thermal-Magnetic 10 kAIC · ABB THQL21100
ABB THQL21100 is a 2-pole 100A plug-in thermal-magnetic circuit breaker for 120/240V branch circuits in compatible Q-Line load centres and lighting panels. Commonly used for large 240V loads or feeder applications where a 2-pole 100A breaker and 10 kA interrupting rating are required; actual suitability depends on panel compatibility, conductor sizing, load calculation, and local electrical code.
What this product is for
The ABB THQL21100 is a Q-Line plug-in thermal-magnetic circuit breaker with 2 poles, 100A rating, 120/240V AC rating, and 10 kAIC interrupting capacity. It is used to provide overload and short-circuit protection in compatible Q-Line load centres and lighting panels.
Use for
- Protecting 120/240V AC feeder or branch circuits requiring a 2-pole 100A breaker.
- Residential and light commercial panel applications using compatible ABB or legacy GE Q-Line equipment.
- Large 240V loads such as sub-feed applications, HVAC equipment, or other equipment where the panel schedule and equipment nameplate call for a 100A 2-pole breaker.
Avoid for
- Panels not listed for Q-Line plug-in breakers.
- Bolt-on breaker positions or equipment requiring a different breaker family.
- Applications needing a higher interrupting rating, special trip function, or different voltage class.
Best for
Electricians and maintenance buyers replacing or specifying a standard 1 in per pole plug-in breaker for compatible Q-Line distribution equipment. This format suits panel work where quick-make/quick-break operation, common trip, and visible trip indication are important.
Installed in
Typically installed in compatible indoor load centres or lighting panels. Q-Line breakers are approximately 1 in (25 mm) wide per pole, so a 2-pole unit typically occupies about 2 in (51 mm) of breaker space.
Why this product exists
This breaker provides a standard plug-in 2-pole 100A protection option within the ABB/GE Q-Line platform. It combines thermal-magnetic tripping for overload and short-circuit protection with internal common trip for multi-pole circuit protection.
Compared with similar products
Compared with lower-amp Q-Line breakers, the THQL21100 is selected where the circuit design specifically requires 100A capacity. Compared with bolt-on versions, this model is a plug-in style for listed Q-Line panel interiors. As typical trade guidance, a 100A breaker is often used for larger feeders or equipment circuits rather than general receptacle branch circuits. Actual application depends on conductor ampacity, termination ratings, equipment markings, and local code.
