General Electric THHQB2120GFT Plug-In Circuit Breaker

General Electric THHQB2120GFT Plug-In Circuit Breaker is a 20A, 240V, 2P 1PH device designed for plug-in installation. It belongs to GE's THHQB family, with the 2120 part number reflecting a 20-amp, 240-volt, two-pole, single-phase configuration. The 20A rating specifies the maximum current it will allow before tripping, and the 240V rating indicates the voltage level at which it is designed to operate. This model provides overcurrent protection for circuits that require two conductors in a single-phase arrangement and uses a plug-in form factor for easy replacement in compatible panels. The THHQB2120GFT designation helps identify the exact GE part for selecting the correct replacement in electrical systems employing plug-in circuit breakers.
