GE THQB2120GFT 20A 2P 240V Circuit Breaker, GFCI, Bolt-On | AmpState

Engineered for reliability in everyday electrical work, the GE THQB2120GFT is a 2-pole, 20-amp, 240-volt GFCI bolt-on circuit breaker designed for panelboards, load centers, and electrical distribution systems. It’s an ideal choice for replacement projects and for stocking spares that keep your BOM aligned with the original GE part number.

Why the GE THQB2120GFT stands out

• Exact, BOM-aligned replacement: Designed to match GE’s original part number for seamless swaps in existing installations.
• 2-pole, 240V protection: Safely disconnects both hot lines to protect multi-wire branch circuits and prevent dangerous arcs.
• Built-in GFCI protection: Monitors leakage to ground and trips quickly to reduce shock risk on outlets and connected equipment.
• Bolt-On mounting: Quick, secure installation in compatible GE panels with dependable contact points.
• Residential and light commercial ready: Suitable for a variety of 240V circuits where GFCI protection is required or beneficial.
• Trusted GE reliability, availability through AmpState: Backed by GE engineering and readily obtainable when you need a precise fit.

What it protects and how it works

• The 20-amp rating provides appropriate protection for standard 240V branch circuits feeding outlets and equipment in homes and light commercial settings.
• As a GFCI device, it continuously monitors current balance between the hot and neutral conductors and trips immediately if a ground fault is detected, helping prevent shock hazards.
• Two-pole construction ensures both live conductors are isolated during a trip, improving safety on shared circuits.
• The bolt-on design promotes a solid, vibration-resistant connection, reducing the risk of loose terminations over time.

Ideal use cases

• Replacement projects in GE panelboards and load centers where a THQB2120GFT is the correct GFCI bolt-on solution.
• Stocking spares to maintain BOM alignment with the original part number for service fleets and maintenance routines.
• Residential or light commercial installations requiring 240V GFCI protection on dedicated circuits or multi-wire branch circuits.
