GE THQB1120GFT - 20A, 1-Pole, GFCI Ground-Fault Circuit Breaker

GE THQB1120GFT is a 20A, 1-Pole GFCI ground-fault circuit breaker engineered for reliable protection in commercial, industrial, and OEM electrical setups. It continuously monitors for leakage to ground and immediately interrupts power to reduce the risk of electric shock, equipment damage, and unplanned downtime in distribution panels and motor control centers.

Why this GE GFCI breaker stands out

• Precise ground-fault protection: detects abnormal current leakage and trips to safeguard personnel and critical equipment.
• Flexible, 1-Pole design: compact form factor that integrates smoothly into panelboards, switchboards, and control panels where space is at a premium.
• Built for demanding environments: purpose-built for industrial, commercial, and OEM applications where dependable overcurrent protection is essential.
• Direct-to-panel reliability: part of GE’s trusted protection lineup, designed to perform consistently in distribution panels and motor control centers.

Ideal applications and use cases

• Panelboards and switchboards in manufacturing facilities where personnel safety and process reliability are critical.
• Control panels for automated lines, conveyors, and machinery where leakage protection minimizes shock risk and downtime.
• Motor control centers and electrical distribution points needing robust, localized GFCI protection.
• OEM equipment where a compact, plug-in solution delivers essential ground-fault safety without compromising enclosure space.

What problems does it solve?

By continuously monitoring for ground faults, the THQB1120GFT helps prevent harmful shock situations, reduces the likelihood of arc-fault and insulation damage from unnoticed leakage, and supports safer, more compliant electrical installations. It also provides consistent tripping behavior, which simplifies maintenance and testing routines in busy facility environments.
