GE THQB1130 - 30 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE THQB1130, a 30A, 120V, 1‑pole bolt‑on molded case circuit breaker built for dependable branch circuit protection in panelboards and load centers. This unit is designed to deliver durable, consistent protection for residential, commercial, and light industrial applications, with seamless compatibility to GE’s OEM panel systems.

• Bolt‑on mounting provides a secure, vibration‑resistant bus connection that stays solid through movement and electrical noise, reducing the chance of loose connections and nuisance trips.
• Thermal‑magnetic trip unit delivers stable, repeatable protection by combining a thermal element for overloads with a magnetic trip for fast response to short circuits.
• Panel/board compatibility works with matching OEM load centers and panelboards, making replacements and upgrades straightforward without compatibility concerns.
• 1‑pole, 30A design protects a single hot‑leg circuit, ideal for dedicated loads or branch circuits in varied environments, from home garages to small commercial spaces.

Why this breaker stands out

Unlike generic subsystems, the GE THQB1130 is purpose‑built to integrate with GE’s family of load centers, offering a cohesive protection solution with predictable trip behavior and solid mechanical stability. Its bolt‑on construction minimizes movement and arcing risks in environments that experience vibration or temperature changes, while the thermal‑magnetic protection ensures you get quick, reliable response to both overloads and short circuits.

Ideal use cases

Use the THQB1130 for replacing a failed 30A breaker in compatible GE panelboards, adding a dedicated circuit in residential wiring, or upgrading an older system that requires a reliable, OEM‑matched bolt‑on solution. It’s well suited for spaces like workshops, utility rooms, small offices, and other settings where a single 30A circuit needs solid protection and easy maintenance.
