ABB THQP Q-Line 2-Pole Thermal-Magnetic Circuit Breaker, 120/240V

The ABB THQP Q-Line 2-Pole Thermal-Magnetic Circuit Breaker delivers dependable overcurrent protection for 120/240V electrical systems. Rated for a 10kA@120 Vac / 10kA@120/240 Vac interrupt capacity, this plug-in breaker uses a Q-Line frame with a non-interchangeable trip range to provide consistent, factory-set protection against overloads and short circuits. Manufactured to UL Standard E11592, it is designed as a straightforward replacement or addition in compatible ABB Q-Line panelboards and load centers, making it a practical choice for electricians handling residential and light commercial panel work.

Key Features

  • Pole Configuration: 2-Pole design for two-pole 120/240V branch circuit protection.
  • Interrupt Rating: 10kA@120 Vac / 10kA@120/240 Vac for dependable interruption of fault currents.
  • Trip Type: Thermal magnetic (LI) trip mechanism responds to both sustained overloads and short-circuit conditions.
  • Frame: Q-Line frame, plug-in style, for compatible ABB panelboards.
  • Trip Range: Non-interchangeable trip range delivers consistent, factory-calibrated protection that cannot be field-adjusted.
  • Voltage Rating: 120/240V rating suited to standard residential and light commercial distribution systems.
  • Packaging: Supplied 1 EA per unit for straightforward stocking and replacement.

ABB THQP115 – Frequently Asked Questions

1) Will an ABB THQP Q-Line breaker fit my existing panel?
The THQP Q-Line is a plug-in breaker built on the Q-Line frame, so it seats in compatible ABB Q-Line panelboards and load centers. It is intended as a direct replacement or an added circuit in those panels. If your panel is a different manufacturer's bus, or an ABB panel that does not take Q-Line plug-in breakers, this is not the breaker for it.
2) What amperages does the ABB THQP Q-Line breaker come in?
Nine amperage choices are offered across the THQP line: 15A (THQP115), 20A (THQP120 and THQP220), 30A (THQP130 and THQP230), 40A (THQP140 and THQP240), and 50A (THQP150 and THQP250). Order by the exact catalog number, since the same amp value appears under more than one part number.
3) I need a breaker for a DIN rail panel, not a plug-in load center - what should I use instead of a THQP?
The ABB THQP Q-Line breaker is a plug-in style breaker built on the Q-Line frame for compatible ABB Q-Line panelboards and load centers, so it will not mount on DIN rail. For a DIN rail application, the Square D C60 UL489 miniature circuit breaker is a DIN rail mount MCB and is the right form factor for that enclosure.
4) The THQP is a Q-Line breaker - is the Square D PowerPacT Q I-Line the same thing?
No. Despite the shared letter, they are unrelated frames. The ABB THQP uses the Q-Line frame in a plug-in style for ABB Q-Line panelboards and load centers. The Square D PowerPacT Q is an I-Line circuit breaker, a bolt-on I-Line style for Square D I-Line panelboards, and the two are not interchangeable in the same panel.
5) Can the trip setting on the ABB THQP breaker be adjusted in the field?
No. The THQP uses a non-interchangeable trip range, so the thermal-magnetic trip is factory calibrated and stays that way for the life of the breaker. If you need a different trip point, you change the breaker, not the setting.
6) Is the ABB THQP suitable for a 240V two-pole load like a water heater or dryer circuit?
It is built for exactly that. The THQP is a 2-pole device rated 120/240V, giving two-pole branch circuit protection on a standard single-phase residential or light commercial service. Size the breaker to the conductor and the appliance nameplate.
7) I need a single-pole breaker for a 120V circuit - is the THQP 2-pole the right part?
The ABB THQP covered here is a 2-pole configuration for two-pole 120/240V branch circuits, so it is not the part for a single 120V circuit. A single-pole option in the comparable set is the Square D Multi9 C60 1-pole C-curve miniature circuit breaker rated 120V AC, though it is a Multi9 C60 series device and will not plug into an ABB Q-Line load center.
8) Can I field-adjust the trip setting, or do I need a different breaker family?
The ABB THQP has a non-interchangeable trip range, so protection is factory-calibrated and cannot be changed in the field - you select the amperage at purchase, from 15 through 50 amperes across the range. If an adjustable or interchangeable trip unit is what the design calls for, that is a molded case family such as the Square D PowerPacT B thermal magnetic breaker rather than a plug-in Q-Line branch breaker.
9) What does thermal-magnetic trip mean on a THQP breaker, and what does it protect against?
Two separate trip elements in one breaker. The thermal element reacts to sustained overload, heating a bimetal until it trips, which tolerates short inrush but clears a circuit that has been overdrawn for a while. The magnetic element reacts instantly to a short circuit or high-magnitude fault. On the THQP this is described as an LI (long time, instantaneous) trip mechanism.
10) How are ABB THQP breakers packaged for stocking?
Supplied one each per unit, so an MRO or maintenance shop can stock individual amp ratings for replacements rather than buying a multi-pack.
