Description
Built for ground fault equipment protection, the ABB THQL1130GFEP2 miniature circuit breaker is rated 30A at 120VAC with one pole and a 10kAIC interrupting rating. It belongs to the THQL series and Q-Line family. It uses plug-on mounting and box lug terminals. Thermal magnetic tripping uses fixed thermal and fixed magnetic settings, with long-time and instantaneous trip functions. It has a single circuit arrangement and one phase.Specifications

Product FAQs
8 answersHow does the 10kAIC interrupting rating affect selection?
The 10kAIC rating describes the breaker's ability to interrupt fault current. Compare it with the available fault current at the installation point, which must not exceed the interrupting rating.
When should I choose a breaker with GFEP protection?
GFEP means ground-fault equipment protection. Choose this breaker when the circuit design calls for equipment ground-fault protection along with thermal-magnetic overcurrent protection.
How does the thermal-magnetic trip operate, and can I adjust it?
The thermal element provides long-time response to sustained overloads, while the magnetic element provides instantaneous response to short-circuit current. Both trip elements are fixed, so selection must suit the circuit without field adjustment of those settings.
How are conductors secured at the terminals?
The breaker uses box lugs, which clamp conductors within the terminals. Prepare and seat each conductor so the lug secures it properly during termination.
What dimensions should I account for when planning the enclosure layout?
The breaker measures 1.36 in high, 3.31 in long and 2.73 in wide. Use these dimensions to plan component placement and reserve space for conductor routing and terminal access.
What does the 30A rating mean on the ABB THQL1130GFEP2?
The 30A rating is the breaker's nominal current rating, not its fault-interrupting capacity. Use this rating when evaluating load current and overcurrent protection requirements.
How should I evaluate the voltage and pole ratings?
The breaker is rated 120VAC and has a 1-pole, single-phase circuit arrangement. Evaluate voltage and pole count separately when determining the electrical requirements for the circuit.
What does plug-on mounting mean for installation?
Plug-on describes the mounting connection, while box lugs secure the conductors. Plan for both the plug-on mounting operation and the conductor terminations during installation.
