Abb THQB1115GFT2 Single Pole 15 Amp Gfci Breaker

Product Description

The ABB THQB1115GFT2 is a single-pole, 15-amp GFCI circuit breaker designed for branch-circuit overcurrent protection with integrated ground-fault protection for personnel. It fits into load centers and panelboards that accept THQB-series breakers, making it a direct-fit option for residential and light commercial electrical distribution panels. Electricians select this breaker when a circuit requires both overcurrent protection and GFCI protection in a single device, reducing hardware count and panel space. The THQB series is a recognized format in the trade for its compact bolt-in footprint and reliable trip characteristics.

This breaker is suited for residential and light commercial applications where GFCI protection is required by code, such as bathrooms, kitchens, garages, outdoor circuits, and similar wet or damp locations. It provides protection at the panel level, covering the entire branch circuit rather than only a single outlet location. Licensed electricians install it during new construction, panel upgrades, or code-compliance retrofits.

Key Features

• Single-pole configuration for 120-volt branch circuits
• 15-amp rated overcurrent protection
• Integrated GFCI function protects the full branch circuit from the panel
• THQB bolt-in footprint for compatible load centers and panelboards
• Combines overcurrent and ground-fault protection in one device, reducing panel space requirements

Compatibility

Designed as an OEM-style replacement or upgrade breaker for panelboards and load centers that accept THQB-series bolt-in circuit breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always shut off the main breaker and verify the panel is de-energized before working inside the load center. Follow the manufacturer wiring instructions included with the breaker for proper neutral and ground-fault lead connections. GFCI breakers require connection of the panel neutral to function correctly — confirm neutral bar accessibility before starting the job.
