General Electric THQL1120GFTNN Circuit Breaker

General Electric THQL1120GFTNN is a single-pole circuit breaker rated for 20 amperes at 120 volts, built to protect a 120V branch circuit from overcurrent. As a member of GE's THQL family, this device carries the model code THQL1120GFTNN and is configured for one live conductor path, providing automatic interruption when the load exceeds the 20A rating. The 20A, 120V specification defines the maximum continuous current permitted on the protected circuit, helping prevent wiring damage and overheating in typical residential electrical installations. In practical use, this 1P breaker commonly protects individual circuits such as lighting or receptacle runs within a home's electrical system, delivering fast, reliable disconnection if a fault occurs. The THQL1120GFTNN designation identifies its exact electrical characteristics within GE's breaker lineup, ensuring accuracy for sourcing and replacement in projects requiring a specific GE part number and 120V, 20A, 1-pole protection.
